Should be fixed now...mostly. The issue is out of my hands really though. The url used to fetch the current worker speed (http://www.continuumpool.com/hashrate.php?worker=) seems to time out most of the time. This is also the case with the RPC, which was taking a huge amount of time to return the current round time for some reason. So I've decided to cache the pool stats (round start time and total hashrate) and run a cron job to fetch them every 5 minutes. This should make the page load noticeably faster now. There will still be errors if the continuumpool site times out but there isn't anything I can do about that, but it should work more often than before now.
