I appreciate the response on WHT.
I think what upsets me about the situation are two things. Firstly I'm amazed at how long it took to resolve the problem. This, of course, is out of GH's hands.
Secondly I was disappointed by the lack of communication. Whithout a monitoring service I might have never learned of the outage. Had I received a timely mail notification I would have had the chance to reroute to another server through my registrar.
My situation does not warrant the expense of 2 dedicated servers with load balancing as I am not a reseller. I run an ultra low traffic site on shared hosting. From GH's point of view I'm small fish.
However, potential buyers that come to my portfolio site are considering spending 4 to 5 figure sums, and that's where downtime becomes an issue, because it immediately communicates a lack of professionalism. I doubt that my last sales contact would have materialized if the buyer had been unable to reach the site on repeated attempts.
I will stick with GH for now. As I mentioned before, I am perfectly aware of the fact that this was not your fault in any way. But I have to admit, my enthusiasm has waned a bit. An understanding of the technical issues does not help alleviate the frustration factor. Better communication would be a help.
