“ On Saturday, June 2nd, we had a perfect storm
of cascading failures resulting in around four hours of lost tracking data.
“ We have commissioned a new database cluster with automatic
failover that we hope to be using sometime next week.

we have learned from this and will rise from the ashes of your data loss like a GLORIOUS PHOENIX.
