I must admit that I'd noticed it had gone missing, but I hadn't got around to commenting its 'Missing' status on the forums. (I only got back from my hols on Monday and I'm still working out the jetlag.)
This site is one of the tabs I regularly have open in Mozilla and check on it at least once a day, mainly since the Rosetta stats where put up there (the Pirates race bringing me back into BOINC for a while).
At first, I thought you had just taken it down for an update, like integrating the Rosetta stats onto the home page, but as it dragged on, I got a bit more suspicious.
I'm quite interested in how the hosting aspect of this stats page work out, especially as you've mentioned bringing it back in-house. How heavy is it to process the stats data as it stands? Is it processor, disk or network bound? What is the outbound network traffic like (in other words, is it practical to host this on an ADSL line with its limited outbound bandwidth). If work permits, I might also be interested in helping out in some way (my job is essentially working with databases, so it might be interesting to get involved in a project like this). I also have a lot of computers round the place that may be useful to host something like this if required.
Apart from this, you have my vote for keeping it going.
