Thanks kuzetsa. The SSL configuration for blockchain.info is broken still so links on nastyfans.org do not work. But I guess they fix that soon.

Distribution 224929 needed many hours to be accepted. The transaction propagation time is also very long. It seems many nodes are not propagating some transactions. I also saw this problem with a nastyfans member purchase order. It was a very simple transaction with even large tx fee but needed 3 hours to propagate to my bitcoind. The result was a expired purchase order.

Are there nodes trying to disrupt Bitcoin network? Or are big miners/pools using new special rules to choose allowed transactions?
