UNPLANNED SERVICE OUTAGES

Possible Email Bounces From Normally-Working Sites

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.

Systems Down

masters12 (grad net computer located in G61) is down due to a bad disk. Grad/Research Net users can use any of the other Grad/Research Net Linux systems until we've replaced the disk. No ETA on the disk replacement timeframe yet.
