Thanks for bringing this to our attention, and for your patience while we fixed the issue. I got the stats system back up last night and it appears to be running smoothly now.
They are having load issues on the stats front-end pages, so some data for some links is not updating or is timing out. Try this link instead - https://stats.foldingathome.org/donor. I have seen fewer timeouts on that one when I search for a specific donor name.
The developer is aware of the problems and is looking into them.
