I just got a response to my ticket that their nodes are facing a DDOS attack and they are in touch with the server center for updates.
Support seems to have gone from very good to pretty shabby in the space of a week.
Their "24/7" online chat support hasn't been working for a good while now and responses to support tickets are getting worse.
Sadly they've just lost me as a customer. I'd rather pay an extra $10 a month to Knownhost and know I was going to get exceptional support and uptime.
Does Knownhost allow porn? I don't own any porn sites, but I do have a forums where pics do get posted from time to time (a la Wickedfire.com)
