As of 12/1 0000z, the web site appears down.
When I saw the site went offline, I started manually monitoring RBN for CQs in the SOTA watering hole frequency. Sure enough, Mike KE5AKL showed up in the list and I worked him. Since SOTAwatch itself was down, I did the next best thing and posted a spot the DXwatch cluster. Unfortunately that didn't generate any takers and I'm pretty sure Mike abandoned the activation.
I saw some conversation about chat sites and such as much as 10 years back, but nothing more recent. What other methods would folks use as a backup in the infrequent cases that SOTAwatch isn't available?
