It seems there have been server problems, your side, so that network connections to sites hosted by you *time out*.
This has happened many times today, as sometimes in the past few years.
Also, it's not been possible to access our websites to change/update them, although we can login.
It's not my ISP - as I've tried accessing my sites via various ISPs and different computers (cybercafes etc) so it seems a problem, your end.
So, just what's going on and when will this problem be resolved?
Also, when (1) will you get back up systems to stop this happening yet again; and (2) have some sort of info on your main website to inform us of technical problems, as many people have asked for over the years?
I may be wrong (and please Dyndaot correct me if so), but it seems Dynadot is more interested in selling Domain Names than in web hosting, and doesn't even keep records of server uptime. Neither does it appear to have server backups, or more importantly it doesn't have any network redundancy for hosted websites in case their connection to their sole ISP backbone fails or there are some technical/bandwidth problems with their ISP.

which says nothing about their latest website downtime. Maybe they're still hungover from the beerfest :)
