There were several short wikitech outages last week caused by heavy machine load on the server that (among other things) hosts the site. In an attempt to distribute load a bit more reasonably I'm migrating that web host to new hardware.
The transition should be fairly graceful as the new host is already up and running. There will be a few interruptions in service, though:
- During the move the new wiki will be read-only. This should only last about 10 minutes or so during the DNS switch-over.
- After the move there will almost certainly be a series of mishaps involving the labs-controlling aspects of wikitech. I'll be scrambling to fix them and don't expect to spend more than hour or so; I'll follow up with another email if the interruption is an longer than that.
- As usual, login sessions will probably be broken necessitating a fresh login to wikitech.
This is scheduled for Midnight GMT Tuesday, February 10th. That's 4PM PST on Monday.
To avoid conflict with the SWAT window, this has been moved back one hour:
01:00 GMT Tuesday, February 10th. That's 5PM PST on Monday.

This move is now complete. Things are working fine as best I can tell, but please file a bug or contact me if you see bad behavior. (But FIRST log out and back in, because that bug I already know about. *sigh* )
Many thanks to Sean Pringle for support with this move, and the other folks on IRC who I roped in at the last minute: Daniel Zahn, Alex Monk, and Bryan Davis. Without them this might well have been an all-nighter.
