My sincerest apologies, everyone. Our wonderful friends at 56k.city have suffered a hardware failure on the Synology NAS that powers this site.
All data that was on here is safe. We just need to replace a power supply.
If you're looking for Skype clients, a temporary server is available here.
We have no set-in-stone ETA on the replacement, but I'm already aware that a temporary solution is being set up to bring parts of the NAS (including our full collection) back online.
