Our server uptime for March 2012 was 99.94%.
There was some reconfiguration done this month in order to improve server responsiveness, though this initially had the opposite effect as it put an unexpectedly high memory load on the server. Over the course of about ten days, the new config was tweaked and a couple of problems were fixed. Performance is now much improved. There was the occasional loss of web site availability during this time but no more than about ten minutes over this period.
The server was also upgraded during this time and now has considerably more memory. Some of the software that runs the web services was also upgraded.
Hopefully we’ll be back to our normal 100% uptime next month!
