Nope you are not crazy. Personally I suspect there is some "security" flag being triggered or a Webserver <--> PHP communication breakdown when the server is stressed. Have any of the hosting providers (for those experiencing issues) been able to explain why "REQUEST_URI" is not always populated in $_SERVER for PHP scripts running on their servers?

Usually, the connector software (suPHP, fastcgi, mod_php, etc) populates $_SERVER including "REQUEST_URI". Additional security modules loaded before or after the PHP connector software could also be a potential issue (by altering what data is available).
