EVERY block solved by AM takes TWO MINUTES to get received into the network. That is about 4 times longer than most other nodes:

this one took just 30 seconds.

The longer it takes for a block to get distributed by the network, the more chance that it will end up orphaned. This is probably also the problem with the small number of transactions in AM blocks, it just takes too long for them to get to the AM farm!

Somebody get AM some better pipes!

they need to get out of the firewall maybe?
