G4 and G5 instances not available in Sydney region for multiple days

0

A few weeks ago I started experimenting with G4 and G5 instance in the Sydney region (ap-southeast2). I needed to increase my quota for vCPU and was able to do that and was able to start and stop instances without issue for a bit over a week.

Starting on Friday, 26 June, I have not been able to start any instance of the G4 or G5 instance type and am always met with the error: Amazon EC2 doesn't have capacity at this time to launch your instances. While we continuously manage and add capacity, availability of your preferred instance type in your preferred Availability Zone is not guaranteed.

I thought this might be transient or some sort of AWS issue, but I have tried a couple times a day for the last 4 days and have been unable to launch an instance. I've raised an account support ticket to ensure my account has not been locked or deactivated, but have not heard back.

I've tried to spin up new instances and confirmed that I can spin up other instance types.

Is anybody else able to start G4 or G5 instances in ap-southeast2? I'm unable to check other regions, as I'd need to get the quota in those regions first.

The error you're encountering indicates that AWS currently doesn't have enough available On-Demand capacity for G4 or G5 instances in the Sydney region to fulfill your request. This is a capacity constraint rather than an account-level issue.

Here are some options to work around this capacity limitation:

For immediate needs:

  • Try launching instances without specifying a particular Availability Zone, which allows AWS to place your instance in any AZ within the Sydney region that has available capacity
  • Submit requests with a reduced number of instances if you're trying to launch multiple instances at once
  • Consider using a different instance type with similar GPU capabilities if your workload allows for flexibility

For longer-term solutions:

  • You could terminate and recreate your setup in a different AWS Region where G4 or G5 capacity might be more readily available
  • Continue trying at different times, as capacity can become available as other customers' instances are terminated

Since you've already opened a support case, you can add updates or additional context about your situation through the AWS Support Center at https://console.aws.amazon.com/support/. Depending on your AWS Support plan, you may also want to review your plan options, as higher-tier plans typically receive faster response times for capacity-related concerns.

Capacity constraints can persist for varying lengths of time depending on regional demand, so exploring alternative regions or instance types may be your most reliable path forward if you need immediate access to GPU instances.

    I appreciate the bot answered this question, but I feel that something is not right. I was able to spin up instances for multiple days in a row and now have been unable to spin up even the smallest instance type in 2 weeks. I struggle to believe that the 4 random days I decided to start this project I always had capacity, and now for 2 weeks there has been 0 capacity. This feels like an account issue.
