We have had some issues with the update servers in US-East for an as of yet unexplained reason. The update servers needed to be replaced three weeks ago and over the weekend the systems became unresponsive due to overload. Both issues are under investigation.

At this point the update infrastructure operates as expected. Unfortunately there is no ETA for a final resolution as we do not yet fully understand why we are seeing this behavior in the US-East region of Azure.

We apologize for the inconvenience.
