Amazon Web Services (AWS) network problems January 16, 2019 (resolved)

Update 9:30 PM Pacific time: the problem described below is resolved, as Amazon is no longer sending data through the problematic route to our servers.

Original post: Our monitoring systems are showing that this evening, there have been short periods of network failures between our data center and some Amazon Web Services (AWS) data centers on the US East Coast. This appears to be due to a problem Amazon is having connecting to an intermediate “Internet backbone” connection in Virginia run by a third party.

This isn’t affecting other connections, so most of our customers are unaffected, and we see no overall drop in traffic.

SSLv3 disabled on all servers

We’ve updated the SSL/TLS security settings on our servers to match current “best practices” for security, disabling the long-obsolete, insecure “SSLv3” in all cases.

Our customers shouldn’t notice any changes. We made this change on our own websites a long time ago with no reports of problems, and nearly all of the largest sites on the Internet have done the same. We’re just mentioning this so that people know to contact us in the unlikely event they do have any trouble.

That said, if you do have any trouble, it’s probably because you’re using a long-outdated, insecure web browser that you should update. You can check your browser by visiting www.howsmyssl.com. If you can’t update it, using a different browser on your computer will probably help.

Brief outage on web03 server October 19, 2018 (resolved)

Between 10:58 and 11:09 AM Pacific time today (October 19, 2018), the “web03” server experienced an outage that led to an interruption in service for some customer websites and email.

The problem has now been resolved, and other servers were not affected. We apologize for the inconvenience this caused our customers.

We’re investigating the root cause (a Linux “kernel panic”) to ensure it does not recur.

Manual spam “blacklist” matching improved

We’ve improved how our “My Account” control panel blacklisting of email addresses works.

Previously, if you added an e-mail address to the blacklist, the “Return-Path” (aka bounce address) header of each incoming message was checked for matches. This was sufficient for most messages, but some messages use a different address in the “Return-Path” header and the “From” address header, which could be confusing.

As of today, both headers (the “Return-Path” header and the “From” address header) are checked when matching blacklist entries, making it more reliable.

As always, don’t hesitate to contact us if you have any trouble or questions.

Mailman mailing list software upgraded to version 2.1.29

Users of Mailman lists shouldn’t notice any changes, but as always, don’t hesitate to contact us if you have any questions or see any problems.
