I have not had a reseller account with Hawkhost. Thus far the uptime I have experienced here at Hawkhost has been essentially 100%. In other words, the site monitor that I use to watch for downtime has never reported an interruption with a window interval of 15 minutes. It is possible that there has been a short interruption but I'm not aware if it has happened. I have had the occasional problem of not being able to access a site but the problems thus far have been network issues or problems with my DSL provider.
At a previous hosting company there were interruptions and all of my sites went down at the same time. In addition, the provider had DNS service running on the same server and therefore DNS failures as well. It really is a no-no to have a single DNS server but many cPanel providers do just that. Here at Hawkhost that is not a problem because they run DNS services on separate systems which is a very nice feature that they don't brag about for some reason. I give Hawkhost extra atta-boys for their DNS setup.
