The OCF directory server went down today (Tuesday 9/15) at roughly 10:20 PM, taking pretty much everything else with it. We're still working on figuring out what went wrong and how to fix it.
We'll post updates here as we have them. You can also find us at on the #OCF channel on the CSUA irc server at irc.csua.berkeley.edu.
UPDATE 9/16/09 3:00 PM: It looks like everything is back up again. If you find anything missing or broken, please let us know.
And to everyone who was wondering, yes, this is why your passwords/email stopped working. This is also indirectly responsible for why you may have gotten funny looking prompts when logging in remotely.
