Block LoadImpact from DDOS'ing tile.openstreetmap.org #288
Yesterday (11/March/2019) one of our caches was effectively Denial of Service attacked by LoadImpact.com when a 3rd party used LoadImpacts service against tile.openstreetmap.org
Loadimpact does not honour the robots.txt exclusion already on the site: https://tile.openstreetmap.org/robots.txt
For clarity for others reading this ticket: The most likely scenario is a customer of Load Impact used Load Impact's Browser session recorder, the site being recorded was using map tiles from tile.openstreetmap.org. The recorded session was then re-played using the load impact service with 1000s of users causing a massive traffic spike.
