As of this evening, I can't connect to Foonetic anymore, and looks like it's the end for good. I guess that I can write: R.I.P.
I still had my PC connected to it earlier today. This morning, less than an hour since the event, I saw these messages, the latter of which referring to what was apparently the very last disconnection from Foonetic (presumably delayed due to time out):
Aug 01 07:08:48 -Global- [Network Notice] spinfire - So long, and thanks for all the fish.
Aug 01 07:24:45 * Disconnected (Connection timed out)
This page claims that the network was registered on January 2009 (not sure that it's the exact month of starting the service): https://netsplit.de/servers/?net=Foonetic
My IRC logs from Foonetic, which I'm lucky to still have, say that I originally connected to Foonetic at "Sat Sep 5 23:29:59 2009" (local time), and then joined the #pckf at "Sat Sep 5 23:30:11 2009". If the final shutdown were to occur just a bit more than a month later, then I'd technically have my 10 years anniversary beforehand.
As for a few more random notes: The Foonetic channel's topic was last set by splsplspl at "Sat Nov 2 13:51:50 2013". The alternative SlashNET channel's topic, which is currently the same as in Foonetic, except for the addition of a welcome to the SlashNET channel, has been set by DHeadshot at "Wed Jul 24 14:54:08 2019".
