This BB and the backup wiki at http://www1.cpdl.org run on a different server operated by another hosting provider, so they will be unaffected.MySQL upgrades will be performed on your server on April 25th at 10:00pm CST.
During the time of the upgrade you may notice temporary down time on MySQL, high load and possible slower load times on your websites. We thank you for your patience while we strive to ensure your server always has the latest software versions for both performance and security.
