Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
The server's hardware has been failing randomly lately, and even Hetzner technicians are telling us that the machine is old af.
I think we should go a with a new machine this time (not a used one), and also ditch physical HDDs in the process. This one seems reasonable:
https://www.hetzner.com/dedicated-rootserver/ax51-nvme
Apparently we can have Hetzner re-route the IPv4 subnet also:
https://wiki.hetzner.de/index.php/Root_Server_Upgrades/en#2._Upgrade_in_parallel_operation_with_take_over_of_IPv4_subnet.28s.29
(We cannot move the Lightning Network nodes to a new IP, AFAIK.)
I carefully read the text again, and if we want to keep the IPs, then they have to put the new machine in the same place as the old one. This means that Centaurus would be in a different DC (DC 11 vs 13).
I also asked around and @maxsan told me that when you change a Lightning Network node's external IP in the config, it would actually be communicated to other nodes and picked up by the network. So it looks like we could change the IP after all.
Considering these facts, I would propose to ditch the old IP eventually and move everything over to the new IP bit by bit, after the new server has been provisioned.
@greg WDYT?
Btw, here are the names of the nearest galaxies starting with the letter D:
@greg Any preference?
Moving everything bit by bit to a new server sounds good.
Regarding the name of the new server, personally I would go with Draco as it the simplest name but the other names are alright too
Cool. I like that one, too. Both short, and also is the name of a rocket, launching things into space. :)
Closing this in favor of only keeping #221 open, as all critical software has already been moved, so Andromeda has been replaced for all intents and purposes.
