Yes there are at least 2 pools creating the blocks.
One is running poolserverj and another isn't.
It was just interesting to see 11 out of 16.
I went looking for the other thread just now and yeah back then (a month ago) it was only 8%
Anyway, as can clearly be seen, for this 2 hours it was 69% of the blocks that blockchain say were relayed by 82.130.102.160
You know about

Looks like 50BTC had a run of luck, 5 of 8 blocks!
The above posters and others have mentioned ETH Zurich, which is a supercomputer project that's optimized for different things than the average mining pool. It's a common suspect here, but in this case you really did see a string of luck from a single pool, you just had (even more) incomplete data only looking at the one site, and got lucky.
Bitcoin is all about luck though, so good one!
