Fastly will be adding capacity at our Sofia (SOF) POP. End-users may observe connection resets as traffic is migrated onto new hardware starting on 10 September 2025 at 01:30 UTC.

Our estimated duration is 3h. 

When this change is applied, customers may observe additional origin traffic as new cache nodes retrieve content from origin. Please verify that your origin access lists allow the full range of Fastly IP addresses (https://docs.fastly.com/en/guides/accessing-fastlys-ip-ranges). Customers with any questions or concerns should contact Fastly’s Support team at https://support.fastly.com.
