+ | The auth server has spun out of control at around noon two days in a row, and needed a hard reboot. I checked the logs, and it just looks like an above-normal but not extraordinary number of hits to the login page. I added "OfficeLiveConnector" to the blacklist, but basically this problem is only going to get worse. | ||

+ | The auth server went down yesterday afternoon. Looks like it was the same problem. I "blacklisted" "Google Updater". There were also a ton (5000) of emails in the mailman queue, all from the past 2-3 weeks; I deleted them. | ||

+ | The auth server went down at about noon today, and I brought it back at about 3pm. At 12:08pm, the server was hit with about 50 login redirects from one IP in about 20 seconds. From then on the server just began spinning wildly. I added the UserAgent string to the blacklist, and installed Cache_Lite. [Actually, I can't get Cache_Lite working.] | ||

I ended up having to upgrade to a 512MB slice in order for the server to not run out of memory. | I ended up having to upgrade to a 512MB slice in order for the server to not run out of memory. | ||
Over the past few days users have reported certificate errors when they hit the auth server ("untrusted site" or "unknown authority") -- I remembered that when installing this cert on the old auth server I had to add an extra file; the "chain file". I added this (SSLCertificateChainFile in the apache config), and the problem seems to be fixed. | Over the past few days users have reported certificate errors when they hit the auth server ("untrusted site" or "unknown authority") -- I remembered that when installing this cert on the old auth server I had to add an extra file; the "chain file".
