My user_timeline feed abruptly stopped without any errors showing


I have a bit of a weird occurrence, I am using user_timeline to display the site’s Twitter feed on the home page (we had a custom designed solution) and it simply stopped working a couple of days ago.

It works locally, it works on other servers, but our Rackspace server simply doesn’t show it 99% of the time now other than the occasional time it shows up but won’t come back on refresh. It worked fine since launch a few months ago.

I contacted Rackspace to see if there was a problem on their end, to no avail. Has anyone experienced anything like this that can offer any insight?
