[overpass] Lots of junk requests

[Roland Olbricht <>]

Dear all,

the French and the Rambler instance have been reported to be 
unresponsive. On the Rambler instance this was due to an app that has 
vastly violated the fair use policy. I suggest to block those requests 
on the French instance, too.

The scale of the problem is around 200'000 requests per hour from a few 
IP addresses, most of them not just similar but identical. I've spotted 
them most easily in the Apache log. I've moved "interpreter" to a 
different file name and use a script with name "interpreter" that calls 
the interpreter if ${QUERY_STRING} doesn't contain suspicious looking 
content.

#!/usr/bin/env bash

TROUBLE=`echo $QUERY_STRING | grep -E 'evil.*request'`
if [[ -z $TROUBLE ]]; then
  ./interpreter_moved
else
  echo "Content-type: text/plain"
  echo "Status: 429 Too many requests"
  echo
fi

Best regards,

Roland
