i have the same problem so how to update/download this cache?

As I said, it's Valve-side. So there is no way to purge it, you just have to wait.

nevermind, it started working just now for some reason (no settings changed in the meantime)

There is a Valve-side cache on the API, if the site is saying it's private, it's because their side hasn't updated yet.

Fixed. Problem was caused by non-latin characters on item name.

looking into it.

Fixed.

Okay, that's utterly bizarre.

I'll have to do some in-depth poking to see what is causing this.

The problem is related to the "Nano" feature, I've tested it in Firefox 18 however and have been unable to reproduce the issue.

Does this occur immediately on load after clearing all cookies/cache etc, or is it triggered when you toggle Nano on?

Valve's item API for TF2 is currently offline and returning a HTTP 503 error code, Dota 2's API is working fine however.

It's a Valve outage, not a TF2B one. So there is nothing I can do at this time, you'll just have to wait it out.

I'll see if I can make the error messages TF2B throws a little more descriptive for these situations.

No ETA at this time.

When the next code release is ready, yes.
