Lately, our ISP (Charter Communications) has been goofy. The cable TV works well. But it appears that the DNS isn't working correctly for Charter. This was confirmed to me by one of my coworkers today.
After spending a half hour on the phone with Charter's tech support, and getting nowhere, I did some searching on my own. It seems that OpenDNS could be an answer for us.
They not only do the right thing with regards to Domain Name Service, they also allow you to filter content and perform customization for your network.
That's all for now. I'm back to getting the router going.
