I've read here multiple reports of people suffering disruption in their forge instances because broken web crawlers.
I have not noticed anything, but: 1. I don't use a forge but cgit (and I cache aggressively), 2. I am blocking a long list of bad user agents at nginx level, 3. I don't have monitoring 😅
So it may be all down to the last point, isn't it?
(although I have never seen any load over 0.16 or so, doesn't mean it is not happening)
@reidrac Yup ... done the same. I got tired of attacks from China so looked up IANA assigns and blocked them. Then IPFire came along and made it dirt simple with a location block addon. Want to block Belarus? Select the country's checkbox and hit save. Gotta love it! (specifically in response to blocking a /16)
