We are about to launch our new customerpanel.ca there will be around 30 minute in about 2 days where you will not be able to login to the cP at all.
Upgrade will be down in 2 phase first one will be to upgrade our current installation with the newest version to add some interesting function on our cP we aren't be able to integrate on the current setup.
The second phase will be completed around two week after we will introduce our cP v2.01 in beta test for few customer and introduced to everyone after our beta phase are completed.
You can see here some screenshot from development about 3 week ago:
There a lot of improvement since but if you have any suggestion or comments please let us know.
We have also disabled other domain than UnderHost.com every TLD like .us redirect now to .com
