Code Interpreter Container Failing (Timeout) on Create EastUS2

Hello, we've been using code interpreter reliably for over a year, but starting on 2/21/2026, containers created in our EastUS2 Foundry instance will intermittently fail. It is easy to reproduce this, by running the below cURL. Try to run it a few times, and it will succeed the first 1-4 times, and then you will hit the timeout. Sometimes the timeout occurs on the second create, sometimes on the 3rd, 4th or 5th. During the timeout, if any other requests to create a container are made, they also hang. This impacts all users if code interpreter is set to auto container creation, with the tool enabled, during normal chat. 

For now we've redeployed resources in US West and do not get the error but do not have quota on more advanced models there so need this resolved ASAP.
