| − | ::JHU Networking has indicated they are testing power transfer equipment in Mason Hall that will affect several buildings, including Malone and Hackerman. They will be cycling power to the buildings, perhaps several times. They expect their outages to be < 10 seconds each.
| |
| − | | |
| − | ::Our CS IT servers that provide you most of our IT services should remain up and running, since our servers have backup battery power. Unfortunately, the JHU network in the building does not. So, you will probably experience brief network interruptions when the power is cycled by Facilities. And each time the power is out, CS services that you interact with (email, web, home directories, etc.) will be inaccessible due to the building's network being unavailable during the outage times.
| |
| − | | |
| − | ::Faculty who run their own servers in the CS Server Room (MH G-29), please note that if you do not have UPS units in your racks (and most of you do not), you can expect your systems will power cycle each time Facilities cycles power in Malone Hall. Please be aware. PhD students who maintain those systems (and perhaps other systems in the building), please keep that in mind as well.
| |
| − | | |
| − | ::The CS computing labs' systems (currently, for the summer, all located in G-61), those computers are not on UPS systems, so those computers will power cycle and should boot back up on their own. But, if you're planning to use our lab systems, because they might go up and down several times during the electrical work time period, you might not want to do your school work on those systems during that time.

| |
| − | ::JHU Facilities is preparing for BGE to test electrical equipment that affects several Homewood buildings. They will be performing this test on Saturday evening, June 26 at 8pm. If you recall, back on May 6, there was a very short power outage that affected our building and others. The testing BGE will be doing is part of their troubleshooting what happened in May.
| |
| − | | |
| − | ::In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening.
| |
| − | | |
| − | ::A short outage of this type will affect our CS servers and IT services in the following way: Although our servers should physically stay running, as they are on battery-backed equipment, because our services require network connections that are controlled by JHU (and not on battery backup), all of our CS IT services will be unavailable during the expected brief outage.
| |
| − | | |
| − | ::Once the power returns, our services should be available again, because the network should be available again.
| |
| − | | |
| − | ::Also, if there is indeed an outage, the CS Grad and Undergrad Lab systems (that currently, you can only access remotely) will power off. However, when power is restored, those lab systems should automatically reboot.
| |
| − | | |
| − | ::Other notes: WiFi and other networking in the building would be unavailable during the outage. Most likely, lights would be unavailable. My group does not maintain J-Card systems, so we do not know how the J-Card readers will perform during a power outage.
| |
| − | | |
| − | ::''For your own equipment, whether it be in your office or the server room, please prepare as for any other planned power outage.''

| |
| − | '''WHAT:''' Most CS IT Grad Net services ''will be unavailable'' due to file server maintenance.
| |
| − |
| |
| − | '''WHEN:''' Thursday, August 15, 4am to 7am.
| |
| − |
| |
| − | '''DETAILS:''' We will be performing upgrade maintenance on our servers, including the department's main file server (named "rtfm") that services the Grad Net (affecting all Faculty, staff, instructors, and CS grad students), and will require downtime for several major CS IT services. The affected IT services will be unavailable on Thursday morning, August 15, from 4am to 7am. Please see below for the list of affected services.
| |
| − |
| |
| − | '''CS IT Services That ''Will Not Be Available'' During The System Maintenance:'''
| |
| − |
| |
| − | * CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. And some CS email services will not be available for CS Ugrad Net users. Incoming mail should be queued by the sender until our mail service is back up again. Outgoing CS mail will not be available to Grad Net users, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the services outage (just not one of our lab computers or compute servers.)
| |
| − |
| |
| − | * IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable.
| |
| − |
| |
| − | * No locally-stored CS webpages will be available. The main CS website (run by WSE) may or may not remain accessible. If you have a personal or lab CS page that we maintain locally in the dept, those will be unavailable. The CS IT Support Wiki and its Notices page will remain available.
| |
| − |
| |
| − | * Grad/Research Net Linux user accounts and home directories will be inaccessible during the service outage.
| |
| − |
| |
| − | * ssh service to our CS Grad/Research Net (masters1 through masters16, gradx, and gradz) will be unavailable.
| |
| − |
| |
| − | * Console (desktop) access at any of our Masters Lab Linux client systems will be unavailable.
| |
| − |
| |
| − | * SMB (SAMBA) File Shares (the CS Office Staff and some others use these) will be unavailable.
| |
| − |
| |
| − | * MySQL service via the mysql.cs.jhu.edu server will be unavailable.

| |
| − |
| |
| − |
| |
| − | '''WHEN:''' Tuesday, August 19 through Friday, August 23
| |
| − |
| |
| − | '''WHAT:''' Subsets of the CS Linux clients will be down for upgrades over the course of the week.
| |
| − |
| |
| − | '''DETAILS:''' In prepping for the new semester, we will be upgrading the CS Dept's [[Linux clients]] (our lab systems and others that are remotely-accessible-only) from Fedora 38 to Fedora 40. This will require having the clients offline during the upgrades. We'll do this in stages, so there will always be some clients available at all times.
| |
| − |
| |
| − | The upgrade schedule for these systems will be as follows:
| |
| − | * On Monday, August 19, ugrad1 through ugrad12 (in MH 122) will be upgraded.
| |
| − | * On Tuesday, August 20, ugrad13 through ugrad24 and masters1 through
| |
| − | masters16 (in MH G61) will be upgraded.
| |
| − | * On Wednesday, August 21, ugradz and gradz (remotely-accessible only) will be upgraded.
| |
| − | * On Thursday, August 22, ugradx and gradx (remotely-accessible only)
| |
| − | will be upgraded.
| |
| − | * On Friday. August 23, any systems that had to be skipped during the
| |
| − | previous days will be upgraded. Our Notices page will have information
| |
| − | about any such systems.

| − | ====Major Malone Power Outage Planned (Affecting CS IT Services) - Saturday, March 30 from 6am to 2:30pm (CS IT Services Outage before and after Power Outage as well)====
| |
| − |
| |
| − | :'''WHAT:''' There will be '''''no''''' CS IT computing services available during an upcoming all-day major power outage for ALL of Malone Hall.
| |
| − |
| |
| − | :'''WHEN:''' Power Outage - Saturday, March 30, 2024, starting at '''6am''' and running until '''2:30pm''' (so, roughly, 8.5 hours.)
| |
| − |
| |
| − | :: Loss of CS IT services - Saturday, March 30, 2024, starting at '''5am''' (one hour before the power outage) and lasting until '''4:30pm''' (two hours after the power outage is completed.)
| |
| − |
| |
| − | :'''DESCRIPTION:''' JHU is planning an a all-day power outage for Malone Hall, and all of our computing services will be unavailable during that time.
| |
| − |
| |
| − | :The actual power outage is planned to start at 6am, Saturday morning, March 30,, and will continue for approximately an 8.5 hours. '''''However,''''' we need to safely bring down our computer servers and clients ''earlier'' than that (before the power goes out.) We plan to bring our systems down that morning around '''5am'''. And although the power to the building should restored around 2:30pm that same day, we will not have all our systems back up and running until approx. 4:30pm, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.
| |
| − |
| |
| − | :{{red|Please read all of the notes below regarding Malone Hall Residents, CS Server Room users, and a list of the CS IT services that will be unavailable during the outage.}}
| |
| − |
| |
| − | ::{{red|'''NOTES TO MALONE HALL RESIDENTS:'''}} During the time of the outage, we're assuming most building lights will be out and the J-Card system might be out too. That might make it more difficult to get into the building during the outage. But with the power out, we're not sure how much need there will be for anyone to be in the building during that time anyway. If you have an office refrigerator, expect that to be out too. If you are counting on your UPS (battery-backup) systems to continue powering your office equipment, keep in mind the expected length of the outage (8 hours) and plan for a longer period of time, just to be safe. And keep in mind that your office phones may be inoperable during the outage. So please plan in advance for this outage.
| |
| − |
| |
| − | ::{{red|'''NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS:'''}} Our server room will be out of power, so our servers will be unavailable. If you host servers in the server room, your servers will be down as well. Plan ahead of time to shut down and to bring back up your servers. Your group is responsible for any systems you choose to shut down before the outage or boot back up after the outage.
| |
| − |
| |
| − | =====Tracking Our CS IT Services Status Updates During The Outage=====
| |
| − |
| |
| − | :Because we will not have power to our servers in Malone Hall, the CS IT Support Wiki, and especially this Notices page ( https://support.cs.jhu.edu/wiki/Notices ) will be unavailable during the outage. Instead, during the outage, we have arranged for status updates to be available at the following website (served at an off-site facility):
| |
| − |
| |
| − | ::[https://csstatus.jhu.edu https://csstatus.jhu.edu] We will update that page soon with this information.
| |
| − |
| |
| − | :(Bookmark that link ahead of time, in case you can't access your CS mail during the outage.)
| |
| − |
| |
| − | :As soon as we're able to do so after the outage, we'll also make this Notices page available again.
| |
| − |
| |
| − | =====CS IT Services ''Un''available During The Power Outage Include...=====
| |
| − |
| |
| − | * DNS resolution (hostname lookups) for all cs.jhu.edu hostnames will be unavailable. This will affect all websites with cs.jhu.edu domain names, even if the website is hosted by someone other than the CS department.
| |
| − |
| |
| − | * CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. And some CS email services will not be available for CS Ugrad Net users.
| |
| − | ** Incoming mail ''should'' be queued by the sender until our mail service is back up again. Outgoing mail will not be available.
| |
| − | ** Outgoing CS mail will not be available to Grad Net users, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the outage (just not from a Malone Hall–based computer.)
| |
| − | ** IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable.
| |
| − |
| |
| − | * '''No''' CS webpages will be available. This includes the main CS website. And, as mentioned above... because we will not have power to our servers, the CS IT Support Wiki, and especially its Notices page will be unavailable during the outage. Please refer to https://csstatus.jhu.edu for status updates during the outage.
| |
| − |
| |
| − | * Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the power outage.
| |
| − |
| |
| − | * ssh service to our CS Grad/Research Net & Ugrad Net Linux boxes (masters1 through masters16, ugrad1 through ugrad24, gradx, gradz, ugradx, and ugradz) will be unavailable.
| |
| − |
| |
| − | * Console (desktop) access at any of our lab Linux client systems will be unavailable.

| − | * Network switches in the building will be without power, so no network connections in Malone Hall.
| |
| − |
| |
| − | * Wifi access points in Malone Hall will be without power and will therefore not be available.

| |

| |
| − | '''8/8/16''' We have been receiving reports of ''email bounces from people/organizations that normally work without problems.'' We think we know what is happening. We recently discovered that one of our CS student accounts had been compromised and was being used to send spam. Even though we disabled the account as soon as the compromise was discovered, several mail server reputation services had already classified us as a possible source of spam. As a result of that classification, some organizations have decided to temporarily reject email from our mail server. We can't predict ahead of time which organizations those are, since there are a variety of reputation services, and individual organizations differ in the ways they make use of reputation information.
| |
| − |
| |
| − | This problem will fix itself automatically over the next few days, as the reputation services take note of the fact that we have stopped sending spam. There's no way to speed up this process, unfortunately.
| |
| − |
| |
| − | This sort of problem doesn't often happen to us. But when it does, it causes headaches like the unexpected bounce messages some people have received. We will be implementing some new processes that we expect will allow us to react more quickly to situations like this, before they reach the point where other organizations stop accepting our mail.
| |
| − |
| |
