Through last week and today I am plagued with timeouts when I use the Infura Ropsten API (Throughout yesterday I did not get a single timeout). I get randomly errors like:
Error: Error: connect ETIMEDOUT :443
When I run my tests about half of the requests to Infura succeed the other half time out. There is no pattern as to which requests fail expect that calls are more likely to succeed and sending tx more likely fail.
