[identified] Starting from 5:00 am UTC, we have started seeing failures to deploy and invoke functions in Dubai region (dxb1). Deployments with Middleware Functions are also impacted in all regions, because Middleware Functions are deployed globally for production deployments. Our team is actively investigating the issue.

[identified] We have rolled out a first mitigation for elevated Build errors. Builds that use Middleware are now excluding the Dubai region (dxb1) from their deployment targets as a temporary measure, and should complete successfully again. We are now working on a mitigation for Builds that are using Edge Functions.
