The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.

You can also use v0 to narrow down the possibilities.

Hi @romainclement, welcome to the Vercel Community!

I'm sorry to hear that your project is being attacked. Let me check with the team about this and get back to you.

Hi @anshumanb,

Did you get some more info about this situation by any chance?

Hi @romainclement, we are still looking into it. But, so far we learned that this is happening because the rules were activated after the account was already paused. That's why there might be some discrepancies.

Hi @romainclement, just wanted to let you know that this case is being worked on by our support team and we'll let you know the findings and outcomes.

Hi @romainclement Weird that IP blocking didn’t help during the attack. Are you sure about the IP range?

Also, during the attack, I guess Attack Challenge mode feature was not there there.

Just to write down some findings:

• Support team has confirmed this was the results of an attack
• Applying filtering rules and attack challenge mode after an account suspension does not seem to take effect for some reason
• After reactivating the account, the filtering rules and attack challenge mode are working as expected
