Last update from Pantheon

Some sites experienced brief interruptions while we responded to an issue affecting appserver stability. We completed a rolling security upgrade and restart of appservers across all regions. All known affected sites have recovered, and the platform is operating normally. We are continuing to monitor the platform and complete follow-up hardening work. We apologize for the disruption and appreciate your patience.
