Mailman list cleanup

March 29, 2022 by Stacey, Craig

Just a heads up that over the next couple of weeks, you may get some mail from me regarding mailman list cleanup. The messages are legit, there should be no embedded links, and they will merely inform you that unless you take action, the list mentioned in the subject will be retired. As a first …

Phishing attack on the lab

March 29, 2022 by Stacey, Craig

A number of people are getting mails from [email protected] telling them of weak passwords and sending them to a site to reset it. It looks very legit, but it is most definitely not. It’s a phishing attack. If you visited the site in question and entered any information, let us (and [email protected]) know immediately.

Network issues fixed

March 29, 2022 by Stacey, Craig

The cause of our issues was an external Denial Of Service attack based around NTP (Network Time Protocol). It was targeted at a server here that used to provide that service to the outside world. We haven’t run an externally-facing NTP server in years, certainly not since we moved from 221. Blocking all access to …

We're troubleshooting a networking issue that's effecting connections on anything inside the MCS network and anything outside it. More details as they emerge.

Summary of the service outage from March 4th and 5th

March 29, 2022 by Stacey, Craig

First of all, the actual cause of the problem was a bad network link.  It was difficult to find, and we were just about to begin migrating the services out of the 221 data center into 240 when it was finally discovered. Here’s the link to Networking’s summary of what happened: https://slack-files.com/T025KBW9U-F025WFY2W-0c97c9 We discovered things were …

And we're back!

March 29, 2022 by Stacey, Craig

More details will come later today once we’ve hammered out what happened, but everything is back (or should be back shortly). Thanks for your patience, sorry for the troubles, and stand by for details. Love, Your humble team of tech monkeys

Status update

March 29, 2022 by Stacey, Craig

Still struggling to get things back up. We’re moving the database services over to a different datacenter in the hopes it will be able to start providing service there. There’s a lot of data to move. I’ll provide updates direct to twitter from this point on, and reserve e-mail/blog posts for more detailed info. If …

MySQL and related services still down

March 29, 2022 by Stacey, Craig

We’re still battling an issue we have yet to diagnose. At this point, we’re not expecting things to come back tonight. We’re working to move the services off the affected infrastructure to bring the critical services back. We’re getting outage pages into place for affected websites. Once we’re through this, I’ll provide a detailed explanation …

Major outage affecting MCS systems

March 29, 2022 by Stacey, Craig

Our primary mysql database server is not allowing connections (or only sporadically allowing them), which is causing a number of services to fail including many websites. We’re working feverishly on getting it working again, but we have no ETA at this point since we’re still not able to get any real diagnostic info after multiple …

Aside from some bugfixes (including improved Exchange interopability), this contains a fix for a serious security issue with SSL certificate validation.
