Between 03:00 and 07:00 (GMT+1) tomorrow morning there will be maintenance on the ISP connection SCoD is on and they say it "might" cause intermittant problems and require restart of router. So translated I'll say it most likely will cause the line to go down, and quite likely not come up again until I yell at their support line.
So in about 6 hours from this post, and for the next four hours, be prepared that it might go down suddenly. I'll check it when I wake up tomorrow to make sure it is up again then.
Possible downtime
