Yesterday at 8 pm locall time, my website encountered an error 524.
Upon some investigation inside my cloudflare account, I noticed a unusual surge of activity from Finland:
I had to create a firewall rule to challenge this request of traffic from this very specific IP address.
I also created a rule to block this same IP inside AWS .
Only after doing this my site was back online.
Why did Cloudflare fail to block this unusual activity?
