Your website did go down because of the load, though - a whole bunch of times in fact! There's even still an entry in the Emerald FAQ about it[1]: "Due to a problem with our webhost 500 errors are increasingly common with new traffic. Please wait a few seconds and try to reload the page, it may take a few tries before you get through." The only reason it doesn't anymore is because you moved to a bunch of really chunky and expensive dedicated servers. http://blog.modularsystems.sl/2010/07/19/emerald-user-statistics/ says that you're using two of http://www.hetzner.de/en/hosting/produkte_rootserver/eq4/ - each of which is about as powerful as some of the older Class 5 Linden Labs servers that host 4 regions each - plus a third unspecified dedicated server. Hazim was using cheap shared hosting. What's more, the guy from the Emerald project who did this knows just how much load the Emerald login screen puts on Emerald's servers, because he apparently pays for and runs them!

Yep, looking at the headers it's definitely static HTML. We've got an Accept-Ranges header, a Content-Length header (both of which you can get from PHP scripts but wouldn't normally), and most importantly an ETag in the same format lighttpd uses for static content. Also, the login page wasn't just making one request for a PHP-generated page from Hazim's website - it was making 20 requests for the same page.
