Website not accessible for all visitors

Hi guys,

I'm not sure wether this question is PHP-related, but because the website I'm having a problem with is written in php I'll give it a go in this forum.

Recently a client of mine told me he had a problem with the website I build for him. He asked me to fix the problem, however I fail to find the cause of the problem. So I hope you guys could help me out!

The website we are talking about is http://www.professionalcapital.nl/ Some of the visitors tell that they can't visit the page. They see the website for just a second and then they are redirected to a 'Can not find page'. I myself don't have this problem and I've tested it on several computers/ browsers. But apparantly a lot of other people do have this problem.

The strange thing to me is that the problem doesn't occur for everybody .. so that would exclude a bug in my php-code, wouldn't it?

Anyway, I hope some of you have a clue on how to fix this!

Thanx in advance, Michiel

Hmmmm ... DNS hijack?

If that is not the reason, then I apologise in advance for scaring you! I only suggest this because it happened recently to the website of my local climbing gym.

it is extremely unlikely to be a php problem.

You need more details from the people that cannot access the site, traceroutes, pings etc. Plus what ISP they use, as it may be a specific to them problem. It does sound like the DNS has not filtered through to everyone - did the site recently move?
