DNS issue

Why the hell was the CAO weather and security camera server suddenly not accessing the internet?

OK, well, not suddenly. And, well, not be completely inaccessible...

Since July 12, the WeatherLink software had not sent updated images to our web site. But, as Dietmar observed, and as I now could clearly see, the WeatherLink software was running, showing local data, obviously intercommunicating with the console (happily without interference problems). But when it tried to upload the images, I saw it pause at the transfer stage, and then suddenly stop. Didn't crash the software. Just gave up uploading.

And, as I sat at the server, in Firefox, I could not access the net.

But the security camera was working!

And I could see the rest of the network from the server.

And everything would be hunkydory if I ran it in DHCP mode.

Took me a few moments to clue in: it was a DNS problem... I pointed our server to the DNS server in the Geogian.net on-site router, versus in our router, and it was fine.

Why the hell would this work for months and suddenly stop on July 12?
