Scheduled an upgrade of MySQL to 5.5 for all servers currently using MySQL 5.1.
Here is the upgrade schedule based on data warehouse location:
- European servers: Apr 30, 23:00-23:59 CEST
- Hong Kong servers: May 02, 03:00-04:00 HKT
- US-based servers: May 03, 04:00-05:00 EDT
During these maintenance timeframes the MySQL service on each server will be restarted. During the restart certain queries may be halted/dropped. Full service will be restored the moment the MySQL service is restared.
