A connection attempt failed because the connected party did not properly respond after a period of time

Question

Prior to the Increase Capacity for Outbound Network Calls update, my Azure websites running in
Standard mode experienced occasional connection attempt failed errors. Since this update the errors stopped but starting on 12/30/14, these errors started up again on both
South Central and East regions:
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond [IP]:80"
It occurs when attempting to consume an external web service over HTTP. This issue is not reproducible on our local environments nor did it occur with our previous shared hosting provider.
On Azure, the same web service call can result in this error or will return a response successfully.
There doesn't appear to be any pattern as to why the same call would work one time but not another.
How can this be resolved again? Any feedback is appreciated. Thanks.
