OK, I have been trying to view the images of Codex Sinaiticus on the codexsinaiticus.org website for the last 24 hours. I keep getting this message:

Too many concurrent connections (> 100.000). The manuscript page is temporarily unavailable. Please try again later.

Who would have thunk there would be over 100,000 people interested in a really old Greek manuscript?!

I guess I will have to wait until the initial interest dies down (a couple days? a week?). What I can say is that the rest of the site looks great (although it does have a few dead links).
