| |
| − | | |
| − | ::JHU Networking has indicated they will be upgrading the OS on almost all their network distribution routers on Dec 23rd from 4am to 6am. There will be a short (5 to 15-minute) disruption during the reboots of these routers, including the one for Malone Hall. This will affect both wired and wireless services at Malone Hall.

| − | ::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 services will be ''un''available due to file server maintenance.
| |
| − | | |
| − | :'''WHEN:''' ''Tuesday, December 28, 5:30am to 7:30am.''
| |
| − | | |
| − | :'''DETAILS:''' We will be performing maintenance on our two file servers, rtfm and barley, that will require downtime for both those systems and several other major CS IT services as well. The affected IT services will be unavailable on Tuesday, December 28, from 5:30am to 7:30am. 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. 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 outage.
| |
| − | ** 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) will remain available, but, if you have a personal or lab 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 and Ugrad Net user accounts and home directories will be inaccessible during the 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.

| − | ====Major Malone Power Outage Planned, Affecting CS IT Service - October 23 & 24, 2021====
| |
| − | | |
| − | :'''WHAT:''' There will be '''''no''''' CS IT computing services available during an upcoming major power outage for ALL of Malone Hall.
| |
| − | | |
| − | :'''WHEN:''' Saturday, October 23, 2021, starting at '''3''pm''''' and running until Sunday, October 24, 2021, sometime around '''6''am'''''.
| |
| − | | |
| − | :'''DESCRIPTION:''' JHU is planning an a power outage for Malone Hall, and all of our computing services will be unavailable during that time.
| |
| − | | |
| − | :The actual power outage is now planned to start at 4pm, Saturday afternoon, October 23, and will continue overnight until Sunday morning, October 24 at 4am. 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 around '''3pm''' that Saturday afternoon. And although the power should be up around 4am Sunday morning, we will not have all our systems back up and running until approx. 6am, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.
| |
| − | | |
| − | | |
| − | :<span style="color:#ff0000">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. </span>
| |
| − | | |
| − | ::<span style="color:#ff0000">'''NOTES TO MALONE HALL RESIDENTS:'''</span> 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, please realize that this is an expected over-12-hour outage. And keep in mind that your office phones may be inoperable during the outage. So please plan in advance for this outage.
| |
| − | | |
| − | ::<span style="color:#ff0000">'''NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS:''' </span> 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]
| |
| − | | |
| − | :(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.
| |
| − | | |
| − | * 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 and through the dbase.cs.jhu.edu server 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.
| |
| − | | |
| − | We will update this page once the reputation scores have returned to normal.
