Site DNS Issues

A few people have reported problems getting to the website or that the website was down. The website was not down, but the problem is there is some kind of rogue server out there propagating invalid IP address information for the website. This is/was getting cached by some of the ISP providers (Spint, Comcast, Version, etc) and as such you may have been unable to reach the website.

DNS is what takes the "packardinfo.com" name and converts that into a numerical address that computers use on the internet. The ISP cache this information for 24hrs at a time to help speed up network connections. So if they store an invalid value, then you cant get to the website until they "refresh" again with the correct value.

Jim had this problem awhile back where his provider always was displaying the wrong IP address for the website. The solution there was to add the real address to his local DNS table on his wireless router so it wont depend on the ISP dns lookup.

My webhosting provider is forcing out an update that should hopefully fix it, but it may take up to 48hrs to propagate.

When I have encountered this problem on my side I switched my DNS host in my computer network setting from the automatically ISP provided one to OpenDNS.org free one at 208.67.222.222.
