On 26 June 2025 from 18:30 UTC to 19:12 UTC, we experienced system errors in our
us-east-1 and us-east-2 regions due to an unplanned data center thermal event. Starting
at 18:30 UTC, our Operations team was notified of a spike in thermal temperature within
several servers within the data centers. Due to the increase in temperature, multiple
storage pools shut down power to the enclosed drives to preserve drive health and data
integrity. Due to the powering down of these drives, several read & write operations
resulted in HTTP 5XX errors.
Upon notification of this thermal event, Wasabi’s Operations Team worked with the data
center team to diagnose and correct the cooling issue and power cycled each impacted
server. Once each server was fully powered up, all services was restored. By 19:12 UTC,
all services were fully operational.
