Woke up to a whole pile of uptime alarms flagging that various websites were not “up” and responding. Azure, Jetpack, Cloudflare – something was clearly wrong.
As you can see from the Apache access logs – hundreds of thousands of hits per minute from the same IP address range – 185.188.204.x
Easy fix to create a deny rule in Azure to block this. I don’t think CloudFlare was touching it.
