Random 504 Errors on the EUCTR #82
Description
Over the past few months we've been experiencing intermittent 504 errors on the EU TrialsTracker.
To date we haven't been able to reproduce them or figure out why. I've noticed that I usually figure out that the site is down when I click on a link someone posts to the website on Twitter. This leads me to believe that there might be some link between the 504 errors and the generation of the preview on Twitter.
