[BUG] Download rate limit at file streaming service #287

Closed Elektronenvolt closed 1 year ago

Elektronenvolt commented 1 year ago

Describe the bug We see a download rate limitation at the file streaming service (SFS) - this slows down or blocks cluster creations and updates. As a workaround we use the offline download feature to fetch images before cluster operations until this is fixed / improved. https://learn.microsoft.com/en-us/azure/aks/hybrid/offline-download

To Reproduce I've re-created and deleted Aks Hybrid clusters multiple times during the day. Finally ending up in download issues of the images. All downloads go over a single public IP. For the first clusters downloads are super-fast, but after a while it get slower and slower

@abhilashaagarwala - as discussed, we can't reproduce the issue anymore as well. I've installed AKS Hybrid on two sites (different Internet providers), enabled offline download, and fetched all images with Get-AksHciRelease multiple times. This issue doesn't show up anymore. Downloads are at the same speed all the time.
