On May 28, 2025, a major incident affected the messaging system in the EU1 hosting location, disrupting functionalities such as imports and automated actions of multiple customer environments. The issue was identified when environments failed to connect to the messaging system, which was experiencing operational difficulties. Immediate actions were taken to diagnose and resolve the problem, starting with a restart of the system to restore normal functions. The restart action successfully reduced the message queue rapidly and roughly 15 minutes after it was cleared. The root cause was determined to be connectivity issues due to the degraded health of the messaging system, to which we have applied an upgrade to ensure future stability.
