Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Whenever one uses the IP xref tool, one request per IP is made to the server. This means, whenever investigating a user with too many IPs, I hit the ratelimit. This means two things:

  1. I get temporarily blocked.

  2. The information that said request is supposed to fetch is never fetched for the last IPs, leading to a bunch of loading icons. Frankly speaking, the info that the request fetches isn't that important.

Could those requests be batched up or something?

I don't think that's the right link... in there I'm referring to something quite different. – BoltClock's a Unicorn Dec 19 '12 at 4:39

Ironic that I got the error while trying to view this very question ;-) – David Z Dec 19 '12 at 5:09

Starting with the next build we'll pause a bit while fetching lots of ips. This should prevent per-ip flood throttling.

Unfortunately, the queries that back that tool are really quite expensive (which is why they're run on demand, over small time windows); running them in a batch isn't really practical, we need to space them out.

Just a note: This still happens at times, though with much less frequency (I had to xref myself and wait a minute-ish for it to happen). It's good enough, though :) – Manishearth Jan 3 '13 at 9:07
