Seeing lots messages like this in my logs while running an import script:
<Thu Jan 4 10:39:15 2018> Failed to open TCP connection to trk.kissmetrics.com:443 (getaddrinfo: nodename nor servname provided, or not known) for host https://trk.kissmetrics.com
It's unclear whether or not the request was retried or discarded. In the context of this script, I would prefer to retry if it failed, but I don't think my code has access to whether or not this call succeeded.
