Hi,

Edit Jul-10-2025 / 10 AM

About to be fixed. Thank you all for the patience.

We’re closely monitoring service health telemetry to ensure the recovery continues as expected. We understand how impactful incidents of this type can be, and we're continuing to open any additional workstreams to expedite recovery and restore availability.

Start time: Wednesday, July 9, 2025, at 10:20 PM UTC
