Had the first outage of searchmysite.net last night:-( Good news is that the the monitoring and alerting triggered. Bad news is that it happened just after I went to bed and I put my phone on Do Not Disturb overnight. Hopefully no-one too inconvenienced. Root cause was the system running out of memory trying to index a ginormous .cbr file. Needless to say some changes already made to prevent a repeat, and more changes planned.
