Can you not reach all websites or just some websites? Can you ping them? Have you tried traceroute? What happens when you try to reach the websites? Is your firewall blocking them? Are you ate home or at work? If at work, maybe there is a site blocker.

test

well, it appears from your traceroute that the failure is either at ams-ix1.sara.computel.nl [195.69.145.35] or at the next step. I was able to get to the website.

Could you do a traceroute to a site you can get to so we can see what should happen. Also, check other failed sites in the same way to see if it happens at the same point.

It would appear that it's not a Linux problem but someone else's problem.

test

I can't see how the problem can be at your end. You are quite clearly getting part of the way - maybe there's a DNS server in your way that is blocking you.

This is mine, we can see that the ams-ix1.sara.computel.nl [195.69.145.35] part of your route comes up on mine. It's just the next 3 steps that don't connect. Try pinging the final 3 steps of my traceroute and see what happens.

I would say that the fact that you can't reach 2 servers nearer them than you would suggest that the problem either lies with them (maybe they can't get traffic from your ip set) or the problem lies with your ISP.

I would email the webmaster of your ISP and supply traceroute details and ping details. Also show successful pings and traceroutes to show that it's not that you can't get any website, just this one (maybe a selection of other failed traceroutes?) Maybe they can track down the problem.

I agree with XavierP, it looks like a problem with your ISP. I suggest trying a different ISP, Netzeo dial up for example, or going to a friend who has a different ISP and see if you can connect to the site just to make sure the problem is within your ISP service.

test

It cant be your site. Even if the site your trying to get to is blocked, i dont think you would be able to do a tracert if its already blocked. eg. hop 1-5.

It could be that the site has blocked you for some reason or blocked a range of IP addresses.
