We are currently experiencing an issue on the servers which causes timeout for 
non-obvious reason. (In some loaded conditions, getting the lag in the cluster 
is taking way too much time. Normally, this operation is done in a blink. We 
are working on a fix.)

Looking at the signature today, I only see the first one as network related:
2 packages failed to many times to retry with key 
launchpadlib.errors.HTTPError:<module>:main:get_versions:iterate_collection:get_collection_slice:get:_request 

Unless some of the root cause behind the other signatures is network related, 
but from the signature itself, it's not obvious.
