As of 06.12.2016 the issue seems to be resolved.

I've seen a lot of people complain about their items not being listed fast enough/listed (or unlisted) with 30 minutes or more delay.

As far as I can see this problem is not on my side, but rather it's because of GGG public stash API being too slow. poe.trade's servers are doing fine, thankyouverymuch.

Some examples:

The server usually is returning less items in a single change. 5k is returned for older change IDs, or when you're unable to "catch up" with the stream.

Here's how it looked like a few days ago:

And here's how it looks like now:

(All times UTC)

As you can see, there's a small period, 03:00-09:00, where it does catch up with the stream.

I believe this issue can only be fixed by GGG. I've already notified them and they should fix it soon.

There's another issue where online API is returning cached data (I think that's the problem?) They are looking into it right now.
