I only see one cookie, for the captcha, and removing that just forces me to solve the captcha again.
The 503 error itself doesn't seem to be cookie related, looks like the site can't keep up with the kind of traffic they're getting.
Also, if clearing cookies prevents errors, it's likely related to caching. Depending on the server configuration, things like authentication cookies will cause the session to bypass caches for certain resources.
