This may or may not be relevant:
On Oct 5th at about 7:30am AEDST (UTC: 4th Oct, 8:30pm) my station went down, hard.
I traced the problem to a change in the server addresses resolved by DNS for weatherstation.wunderground.com
If your station uses any hard coded IP addresses to report, or if your DNS server is still resolving to the wrong IP address to report to, it will be offline.
Options:
1. wait to see if the DNS issue resolves as changes propagate.
2. Check with station supplier to assure hard coded IP addresses are not used. (If so may need a firmware update)
I had swapped to a hard coded address a couple of years ago on my home-coded station due to a DNS bug I couldn't fix, and it came back to bite me. Fortunately the bug seems to have miraculously resolved, so I am switching back to DNS IP resolution (when I can get up the pole!)
