Hello Karsten,
I'm sorry for the inconvenience but our servers have been up and running all that time. There hasn't been a single downtime. Our technical support has just responded to you via the ticket that you created. We will need log information from you to investigate why your computers cannot connect to our servers. If our servers had been down for 6 hours this forum would have already been flooded with reports from other users.
As for responding time - please , note that we have our
support policy that states that Pro users receive technical support within 2 hours during the
business working hours. Our business working ours are Mon-Fri 9 am to 5 pm EST (Eastern Time).
Anyway, we will do our best to help you figure out the issue, but please be informed that our server uptime have nothing to do with it at all. It's very unlikely that we (or other customers) wouldn't have noticed such an extended downtime given the fact that our servers are being monitored with 5 min (and sometimes 1 minute) interval.
