Our trueAnthem Twitter application (https://dev.twitter.com/apps/5373544/show) running on a Digital Ocean VPS at IP address 107.170.31.104 began experiencing connection timeouts making Twitter API calls early this morning.
“Error:Get https://api.twitter.com/1.1/statuses/show.json?id=431451679406706688: dial tcp 199.16.156.231:443: connection timed out”
We can no longer ping Twitter IP addresses from this server but we can ping Facebook IP addresses.

We have temporarily moved our application to Heroku and it is able to access the Twitter API without issue.
Our IP address, 107.170.31.104, appears to have been blacklisted by Twitter.
Why has this happened and what must we do to get our IP address un-blacklisted?
Regards,
