A small number of customers may still see intermittent push failures, and work to restore those is ongoing.

Between approximately 12:00 UTC on 3 October and 07:30 UTC, customers in Europe (eu-west-1) experienced intermittent failures when pushing NuGet packages.

We have applied a change to the affected service and confirmed that package pushes have returned to normal.

Pulling and downloading packages was unaffected throughout, as were all other package formats.

Work to restore normal NuGet package pushes for customers in Europe (eu-west-1) is still in progress. We will confirm here as soon as the service operations return to normal.

We are continuing to apply the change needed to restore normal NuGet package update for customers in Europe (eu-west-1). Pulling and downloading packages remains unaffected.

We have identified the cause of intermittent failures when pushing NuGet packages for customers in Europe (eu-west-1), affecting some package uploads since approximately 12:00 UTC on 3 October.

Pulling and downloading packages is unaffected, as are all other package formats. We are rolling back the change responsible.

Retrying a failed push may succeed in the meantime.
