A few days ago, my Raspberry Pi server that was hosting this site/capsule died. (I'm pretty sure the Pi itself is fine, the SD card is definitely dead though)
Something I so far haven't identified started making the Pi unresponsive and in a panic I pulled the power while it was still doing things to the SD card disk. Thankfully, I at least made a backup of some of its content as of a few months ago. Eventually the Git and IRC servers will probably be brought back online, though there's no ETA as of writing.
