DESCRIPTION:In July 2nd 2019\, a change was made in a Cloudflare's firewall
  rule to validate query parameters in URLs. A couple of minutes later\, fi
 rewalls started failing world wide and reporting a 100% CPU usage\, which 
 in turn dropped 80% of requests made to Cloudflare's CDN\, breaking a sign
 ificant portion of the internet for about 20 minutes. The cause? A small r
 egular expression that for most would seem innocent:\n.*(?:.*=.*)\nJoin us
  and get to know\n\n- Why this incident happened\n- Why this regular expre
 ssion is not as innocent as it seems\n- How the outage could have been pre
 vented\n\nSpeaker(s): Maestro Miguel Sanchez \n\nVirtual: https://events.v

X-ALT-DESC:Description: <br /><p>In July 2nd 2019\, a change was made in a 
 Cloudflare's firewall rule to validate query parameters in URLs. A couple 
 of minutes later\, firewalls started failing world wide and reporting a 10
 0% CPU usage\, which in turn dropped 80% of requests made to Cloudflare's 
 CDN\, breaking a significant portion of the internet for about 20 minutes.
  The cause? A small regular expression that for most would seem innocent:<
 br>.*(?:.*=.*)<br>Join us and get to know</p>\n<ul>\n<li>Why this incident
  happened</li>\n<li>Why this regular expression is not as innocent as it s
 eems</li>\n<li>How the outage could have been prevented</li>\n</ul>\n<p>&n
