We had some downtime of the forum today. The cause was “death by backups”.
In addition to the N backups we export offsite, we also keep 5 rounds of backups in local storage. The quick growth of the community means the database is growing quickly as well, and times 5 for the backup. This morning while trying to perform the backup, the web application failed to perform a 6th backup (it does the Nth+1 before removing the Nth) and instead of just failing the web application locked up and had to be manually restarted.
As a consequence of this failure, we will move this forum to a better location, with more hardware available, and also with a larger team that can watch it 24x7.
Apologies for any inconvenience this may have caused you.
