I went to stackexchange.com and clicked on SO. After a few minutes I got a message saying "We have detected too many requests from this IP. If this is an error contact us." That was the second SE page I tried to visit. Second only to SE.com

I moved to another machine and it's working now. The first machine usually works, I don't know if a got assigned a blacklisted IP or what. Anyone know what's going on?

EDIT: I would really rather not post my IP on the web, but if a diamond or dev asks I'll email it.

EDIT 2: I looked at badp's dupe suggestion and can verify that I have no scripts frequently calling SO.

    Do you know the IP of the first machine?

  • @waiwai933: They are on the same LAN. Do you mean the external IP?

  • Are your machines all sitting behind a NAT'd LAN with a single WAN IP address?

  • @Kev: I believe that to be correct. So I don't know how they could block my IP and it only affect one machine... Just checked again, the first machine works now.

There is a temporary automatic ban that is put up by our HAProxy instance when you hit our rate limiter. It should only last about 5 mins. If you'd like us to take a look we'll need the public IP at the time you can email to george AT stackoverflow DOT com

    @ShadowWizard Ins't it like wondering why a speed limit is public on signs? Commented Aug 25, 2016 at 12:53
