MetaData Fails: The service is unavailable.

First Noticed my .Net-Requests for the MetaData are running into TimeOut.
Gave the WebRequest-Preview Func. at Documentation a try and got this:

Screenshot w/ Request & Error:

Am I alone with it or others got failures too ?

Weird. Working here:

Sometimes It’s working, sometime not.
I made a workaround for me: Serializing the MetaData to an Json-File and load this. Update these files every x-days.
I noticed that the metadata-requests causes a “high” bandwith usage a few requests and faster as I thought these causes ~75MB xD
