Snapshot growth caused an outage on git.sr.ht
git.sr.ht’s ZFS snapshots grew to consume all available disk space. This is normally an understood pathology of the server configuration, but due to a change in billing with Twilio, our paging script did not alert the operators to the imminent issue. It seems that there is not a grace period with Twilio; they reported the billing issue to us only yesterday.
The issue with git.sr.ht has been resolved, the bill has been paid, and we are researching ways to avoid this occuring again in the future. (15:00 — May 14)
