Title: End of the BTC world as we know it? :)

Interesting routing issue with blocks over the last 2 hours ...

11 out of 16 said they came from the same IP in Switzerland :)

The IP they show is not always the IP that actually mined the block.  Could be their listening nodes having routing issues to EU right now, and that particular node happens to be their best connection to any blocks generated overseas (all of Deepbit, 50BTC, etc.).

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

Not again. You are probably the 100th person to "find" this.

It's the ETH Zurich, they are running a "super" node with about 1.500 connections and can therefore forward found blocks than the miner himself.

Edit: See here, the one running the node is even on the forum: https://bitcointalk.org/index.php?topic=113715.msg1229314#msg1229314

You know about http://blockorigin.pfoe.be/index.php, right?

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!

Yeah that thread says '10%' a month ago - but it was something like 8.x%

Today's is 69%

Still nothing important. On 28.09.12 they made 100% for 70 minutes:

Really, its just the best connected node we have.

If more Universitys would run nodes like that, we would have solved the Blockchain size problem.

So this is really a good thing.

Um - no that's 100% for 5 in a row (35 minutes)
Or 78% of 9 blocks for 49 minutes ...

Yes - again - it's a routing issue as I said in the first post.
Of course meaning that some bitcoind on the net is WAY more connected than anyone else - and passing along blocks very fast.
The fact that at least 2 pools (as I said further up and had already checked before I posted) produced the blocks proves that also.

I believe they also skip verification of blocks as well.  So if someone connects to them, and sends a block their way, they IMMEDIATELY send it along to blockchain.info and whoever else wants it.  That's part of the reason they are the first to relay so many of them.
