[Bug] Beta cluster reports 500 for mobile pages
Closed, DuplicatePublic

Description

Steps to Reproduce

  1. Visit https://en.wikipedia.beta.wmflabs.org/wiki/Barack_Obama in Chromium and see that it works
  2. Visit either of the following in Chromium and see that it returns a 500:

Sometimes I get a friendly 503 error message:

Request from 73.181.4.128 via deployment-cache-text05 deployment-cache-text05, Varnish XID 26439909
Error: 503, Backend fetch failed at Thu, 29 Nov 2018 16:33:49 GMT

Usually just a browser 500. I have caching disabled. I can't reproduce in Chrome, Firefox, or Curl. Is it just me? This has been happening sporadically for about a week.
