False Positives on Downtime due to Maintenance
Incident Report for Clerk.io
Today we have performed some maintenance operations on our caching infrastructure.

This had not had any impact on our uptime which is 100% for the day but it caused our monitoring system to think that we had issues and thus falsely report downtime.

If you have closely monitored our responsetimes you might have noticed spikes when we have swapped out cache instances.
