Coinking.io are now merged mining. I believe ipominer and multipool are also in the works.
Stated on the Ipominer site:
Dec 26 5:00 PM Viacoin forked and is currently disabled for mining and payouts until it can be resolved.
Yes, I contacted them: The network is fine, but any software clients that were not upgraded to 0.10.6.x have been left behind. This is because auxpow (merged mining) is a hard forking change so once the rules come into effect, old clients cannot proceed with the new rules. As I wrote in a previous post, most miners and all the important services like Bittrex, Bter etc upgraded before the network transitioned. It just happened a little sooner than expected.
My last communication with ipominer today is they will migrate to merged mining.
