I'm sure that doesn't exist. I've had my site in the front page several times and I never had a problem. I agree I'm a competent sysadm and there's a peak on visits often in a short period, but my server is not as optimised as it could be and it did just fine.
I think what we have here is a server or a web app poorly configured.
What percentage of websites would you think are cared for by a sysadmin at least as competent as yourself, who dedicated at least as much time as you did?
