    Update

    Ambient temperatures in the London data center have returned to near-normal levels. An HVAC technician is on site this morning to complete repairs on the remaining air conditioning unit and to verify the integrity of the other cooling systems in the facility.

    We will continue to monitor the situation closely and will provide a final update once all systems have been fully restored and verified.

    Technicians are on site actively working to repair the rooftop condenser and restore the facility to normal operating temperatures. We will continue to provide updates as the situation develops.

  • Identified
    Identified

    We have confirmed the source of the issue: a failed condenser unit on the roof of the data center, compounded by a separate fault with an air conditioning unit inside the facility. Combined with the ongoing heat wave, these failures have caused ambient temperatures to rise to levels that are triggering thermal throttling and, in some cases, thermal-related crashes on affected hardware.

    Investigating

    We are currently investigating hardware issues affecting our London data center. At this time, network connectivity is not impacted, though some hardware in this location is experiencing problems.

    Our team has identified that ambient temperatures in the facility are running 15-20% above recent average, which we suspect is related to the ongoing heat wave in the region. We are working closely with the data center's NOC to confirm the root cause and resolve the issue as quickly as possible.

    We will provide further updates as more information becomes available. Thank you for your patience.
