Fabric Notebook Session Is Not Getting Created And Throwing Error

[suriaprakash]

I'm trying to run a notebook and the session creation runs for ~10 minutes and throw the error below. Usually the session creation happens in 1-2 minutes. This started happening from 16th July 2024 late night. Initially session creation was taking more than 8 minutes but was getting created. But on 17th morning, session itself was not getting created and below error is thrown.

We experience this quite often. Today it's very bad. We're not able to create any session. Retried many times. The error arrises within a few seconds.

Ondersteuning en status Microsoft Fabric | Microsoft Fabric says that all services are up and running. They are clearly not.

This restricts our production work enormously. I cannot imagine that we are the only Fabric customer that's facing this issue. Is this issue is properly being addressed?

Our Fabric environment is in Western Europe.

Hi @suriaprakash ,

Use high concurrency session instead of standard session and check.

I hope it will be helpful.

Thanks,

Hi @suriaprakash ,

Please try again, there was a problem with some features in Americas and Europe, now fixed.

Hope it helps!
