One of the Amazon AWS Datacentres had a "thermal event" yesterday afternoon (we are guessing an air conditioning failure) between 17:30 and 19:30 UK time. This issue affected approximately 10% of our Alpha Tracker clients whose systems became temporarily unavailable. We are sorry about that.
Amazon recovered their environment quickly and all Alpha Tracker systems automatically recovered by 19:30 last night.
If you need any more information, please do call us on 0333 301 1010 as usual.
