Cloudfront Blocking IP ranges

Does anyone know the best way to get a hold of Amazon and get out off
the naughty list on Cloudfront? I've got some ranges that appear to be
blocked totally by Cloudfront.

Thanks in advance

Hi Quentin,

Have you had luck finding a Nuestar contact? Last time I searched I came up empty. Almost all the sites never respond when we put a ticket/email in saying we are blocked. We are likely going to start sending certified mail from legal and see if that gets any attention. It’s causing a lot of grief to say the least.

I’m still doing digging but have you seen a difference in peering vs transit? I’ve got a couple sites that appear to work via transit and not peering, which if it’s a Cloudfront error makes zero sense to me.

Thanks

Hi Brad,

We have been experiencing the same issue over the past week, with all our ranges seemingly affected.
I reached out to AWS through abuse@amazonaws.com and peering-to@amazon.com.

Below is the response I received:

Thank you for your e-mail. This could have a multitude of root causes, the 403 is quite general. One cause is of course the AWS WAF either from customer specific settings or source reputation classification.
I would advice to contact the site admin to see what the cause is, we do not have access to check the application level. For the reputation classification I would advice to contact for instance Neustar to confirm the current status, and work from there.

However, I find it impossible to contact all the individual sites that are no longer functioning for us.
If anyone has a better solution, I would appreciate your input.

Thanks,
Quentin.
