URLFetchService getting timeouts

[Daniel Florey]

Hi,

since ~10 days we are getting a lot of "hanging" requests when using URLFetchService to upload files to our own servers.

It used to work just fine for the past years...

We can upload to our servers manually from our end without any issues, so it looks like an App Engine issue to me.

Anybody else affected?

Regards,

Daniel

Could you post a screenshot of a trace for a request which is timing out? It will help to be able to see the individual RPC timings.
