a2-highgpu-1g VM instance is currently unavailable

[abayb]

Whatever zone I chose I can't get a2-highgpu-1g. Same issue for a few weeks. Can confirm that project has GPU quota.

The error: 
The zone 'projects/product-label-359922/zones/us-central1-a' does not have
enough resources available to fulfill the request. Try a different zone, or try
again later.

Hello @abayb,

Welcome to Google Cloud Community!

This is one of the common resource errors when requesting new Compute Engine resources.

Resource availability error occurs when you try to request new CE resources specially in a zone that cannot accommodate your request due to the current unavailability of a Compute Engine resource, such as GPUs or CPUs. This error only applies to new resource requests in the zone.

Please also note that this error is not related to your CE quota and only applies to the resource you specified in your request, not to all resources in the zone.

To resolve resource error

In general, the best way to resolve a resource error is to retry the request in a different zone, at a different time, or with a different VM configuration. If the error message you received included a reason field, you can find specific remediation recommendations to help you resolve the error in the Resource error reasons and recommendations section of this document.
