Just sayin', is all 
Actually we have got 4 days of server work ATM so there will be a shedload of stuff to look at soon... Until the project is finished it isn't practical to look at details, we might find that the error gets fixed by some other job. With luck.
It sounds to me like the server app on one box got glitched, so we need to wait until they are all upgraded then work out if the error is still there and then if it's an Apache or Nginx or Varnish issue etc etc. Give us some time please............. Sorry to be techy and unhelpful but it's the middle of a project and the straight answer is that nobody knows nuffin' right now
