The pool is working, just that the front-end is down so you can't register and set up workers. You can still solo-mine though (it started to get slow, so I had switched to another coin, but before writing this post I switched back to LPC and found a block in 30s, nice).

I solo-mined with 730 kh/s throughout the night and found 13 blocks + 4 orphans. It seems the net hashrate is going up though, since it was more than an hour each between the last four blocks I got.
