I recently closed a channel, no issues there. Based on my rating history (some metric generated by lnd-manageJ), the node simply did not perform well. The rating was OK/good until around January 22nd and dropped a lot afterwards. Note that the rating takes previous performance into account, so the actual change may have happened way before then.

When the project started, FTP was still in active use und most other mirror servers had similar names. FTP still works, by the way.

Shortly after I made http://ftp.halifax.rwth-aachen.de/ a Tor relay (up to 20 GBit/sec!), rsync access to openEuler's main server in China stopped working. It's still accessible from other hosts, though. I blame politics.

I wrote down my thoughts/rules on how I'll set inbound fee rates on my #LightningNetwork node c-otto.de once I start using lnd v0.18:

If you have a channel with c-otto.de and want to move funds to my side of the channel, you might want to deposit some sats to Kraken (and withdraw on-chain?). I have lots of liquidity to Kraken and configured a fee rate of 0ppm. #LightningNetwork

I'm pretty confident ftp.halifax.rwth-aachen.de will receive a hardware upgrade soon, thanks to a sponsor I'll name once it is official. The nostr relay (wss://ftp.halifax.rwth-aachen.de/nostr) will also benefit from this!

~75 TByte HDD disk space
several TByte SSD disk space (for caching)
192 GByte RAM (maybe 256 GByte, we'll see!)
at least 20 GBit/sec internet connectivity
7 years of warranty with on-site support

As before, the server will be hosted at RWTH Aachen University (sponsoring power, cooling, network).

Up and running, I think

There might be a new relay at wss://ftp.halifax.rwth-aachen.de/nostr adding 20 GBit/sec to the network. I'll reconfigure, restart and migrate the relay until things are settled, but please feel free to give it a try!

One important limitation: I'd rather not add a new DNS entry for the host and can't dedicate port 80/443 to the service as the host already offers http(s). It seems relays require websocket at the root, though?
