This seemed great, until I popped $5 on it yesterday, made one query, then came back to it this morning and I think it's been "HackerNewsHugged" as it's incredibly slow, and my $5 credit has vanished .
I think so, they had some sort of network issues today,my client did the same thing on and off for most of the day, but it seems to be solved now and all my credits and history are there again.
