My wife and I have a VPS on Knownhost hosting about 10 domains. A number of those domains seem to have DNS issues. Originally, I thought it was an issue with Comcast, as at home if I changed my router's DNS servers to Google it could pull up my websites just fine. However, after trying on my Android phone on T-Mobile where it won't load them and talking to a Comcast tech, I'm wondering if it's on the Knownhost side. Two of the websites in question are paulcutler.org and silwenae.org. According to Comcast, something is wrong with the DNS server - when they try with their tools they are getting intermittent server fail responses and timeouts. Does anyone have any suggestions of things to look at or try or should I file a ticket with Knownhost? Thanks.
