My cgminer started falling back to a backup pool and no longer connecting to the Waffle EU server. I see in my firewall logs that it tries to connect to 206.223.224.225:3009. Is that address related to Wafflepool and how so? It shows on whois lookup as a residential cable in Montreal, Canada. If I restart the cgminer it connects to Waffle EU normally but the same thing happens after a while.
I saw this as well with the same IP. Myself and a couple other people are trying to track down the problem on #wafflepool
My theory is dns hijacking
I've set up some network capturing hardware to try and figure out what happens
