A week ago Justin McAllister (K5EM) emailed me asking if I had any interest in taking over the gaprs.net domain, since lately he's been forwarding users with feature requests to aprs.he.fi anyway. The ownership of the domain has now been transferred and pointed to my site (although it might take until tomorrow before all DNS caches have obtained the new IP address). Thank you for the support and donation, Justin!
To make the site's URL even shorter and easier to remember, I've also obtained aprs.fi and pointed aprs.he.fi to it. That's only 7 characters to spell and remember. Old links will continue to work for the foreseeable future. The downside is that browser cookies don't work over domains, so you'll need to log in and set up the options again. Sorry about that!
So: the new "official" link is aprs.fi.
Gaprs.net and aprs.he.fi links will continue to work as before.
As I am writing this, the site is running on batteries (they're testing the UPS batteries, and after that, the diesel generator).
