The forks were due to the short 60 second block timing, and that the node was communicating with every other node in that minute. This worked well with 50 nodes on testnet, but did not work when scaled up.  The Proof of Time algo was a great idea, to reward loyal forgers, but it is a bottleneck at present. 

I was running a test of the windows wallet, and my computer showed over 200 TCP connections to nodes on port 6040, which were being refreshed constantly.  It also slowed my internet connection down for browsing. 

I cant give you an exact time for the network to be up again, but I will tell you when we start testing the windows node/wallet.
