A denial-of-service attack floods a site with traffic so that legitimate visitors cannot reach it. A distributed attack (DDoS) comes from many machines at once.
WHAT YOU WILL SEE
The site becomes slow or unreachable Bandwidth consumption far above normal Resource limits hit constantly Access logs showing enormous numbers of requests, often to one specific URL
WHAT WE DO
Our network has upstream protection that absorbs or filters large volume attacks. For attacks targeting a single account, we may temporarily null-route or rate-limit traffic to protect the rest of the server.
WHAT YOU CAN DO
Put Cloudflare in front of the site. Its free plan absorbs a great deal of attack traffic before it ever reaches us, and its "Under Attack" mode challenges visitors during an incident. Enable caching so that requests that do get through are cheap to serve. Block obvious offending IP ranges, though rotating sources limit how well this works. Make sure wp-cron and xmlrpc abuse are not amplifying the load.
WHAT TO SEND US
Open a ticket with the time the attack started, the URL being targeted, and log extracts if you have them. Specifics let us act faster.
