For the last year with the SRE team we developed measures against DDoS attacks. The DDoS attack resistance has increased from 850k RPM (requests per minute, e.g. search and authorization) up to 5+ million RPM. And also with the Core team we have improved the Server System Infrastructure and Data Storage. More than that we have cut the Cloudflare and AWS monthly costs up to 30%.
