Request flood from 203.0.113.99

One IP hit the rate limit 50 times in a minute: an attempt to overload the site.

What to do

The rate limit is doing its job; check the site stayed responsive.
If it continues, block the IP at the hosting provider.

Demo: Acknowledge and Resolve are switched off here. In the real dashboard they work.
