Which Cloudflare product does this pertain to?

Section that requires update

Request

What needs to change?

The Request section does currently not mention that you'll see firewall entries with worker as rule ID when the Workers anti-abuse protection has kicked in. Currently customers may be quite confused when they suddenly see a lot of worker firewall entries, as they won't know that it's caused by the anti-abuse protection.

Here's an recent example of a customer who suddenly saw a lot of worker firewall entries, but wasn't aware that it was caused by the anti-abuse protection:

Here's the response I gave for reference:

How should it change?

The Request section should include that the internal worker firewall rule is used by the Workers anti-abuse protection. Currently the worker firewall rule is nowhere mentioned in the documentation, so customers running into it may be a bit confused and not know what to do about it.

Additional information

Not necessarily related to the documentation, but I would suggest Cloudflare to implement some kind of automatic notification when the anti-abuse protection has kicked in for a customer. If for example, a customer is using Workers a lot internally for mission-critical work, it would help a lot if Cloudflare immediately notified them of traffic being too high and that they should immediately contact Cloudflare for a limit raise. Currently, Cloudflare will just drop a lot of requests without any notification, leaving customers completely clueless.
