Degraded Dashboard and Terminus Performance
Incident Report for Pantheon Operations

At 14:00 UTC 20 May, a large spike in DNS traffic was observed. Our on-call engineers were alerted to a slowness in dashboard load times and terminus command completion. Engineers identified sites that were causing an increase in DNS traffic and mitigated the behavior resulting in a return to normal traffic. Some sites were impacted for over 30 minutes while service was restored at 17:07 UTC.

We have identified some improvements that will help us detect and prevent similar issues in the future.
