Current status: We’re carefully rebalancing traffic across all affected infrastructure in the region, while monitoring the corresponding health telemetry, to ensure the environment enters into a balanced state as our remediation efforts continue. We’re proceeding as quickly as possible and this incremental approach will also help us identify whether any additional actions may be required to ensure longstanding recovery.
Scope of impact: Any users served through an affected section of service infrastructure in the North America region may be intermittently impacted.
Root cause: A portion of dependent service infrastructure in the North America region isn’t processing traffic as expected.Next update by: Thursday, January 22, 2026, at 11:30 PM UTC
