Re: csswg.org & dev.w3.org/csswg Planned Downtime

The upgrades are complete and as far as I can tell all services are running normally.

This was a fairly extensive upgrade that required a lot of configuration changes[1], if you notice anything acting differently on the server, please let me know immediately.

Hopefully this will alleviate some of the performance issues we've been having with the server lately.

[1] For the curious, the server is now running Debian 8 ("Jessie"), including new versions of Apache, PHP, Python, and a switch from MySQL to MariaDB. I also upgraded the hardware (more CPU and more RAM) and switched to a different virtualization system (KVM vs Xen)[2]. In addition to getting more horsepower, the server picked up a nice performance boost from the new virtualization engine and has a lot of new security features with heavier-duty crypto. The user authentication system was also upgraded to use stronger hashes for password storage. Password hashes will auto-upgrade the next time you log in to the server[3], so if you care, log out of either the wiki or Shepherd and log in again.

[2] The server is hosted at Linode, and they completely rock. They frequently upgrade their hardware and systems for free. If you need a server, I can't recommend them highly enough:

[3] I can't batch upgrade the password hashes because i never stored passwords on the server in plaintext (and never will), so I don't have the source material to re-hash the current password database (unless I ran a brute-force attack against the old database). During log-ins is the only time the server sees raw passwords (and only over HTTPS) so it takes that opportunity to re-hash the password if an older hashing algorithm was previously used.
