Something's wrong with Ubuntu. Since I've upgraded to 13.10, I can't access some websites for no apparent reason.

I've tried everything imaginable to solve this problem :

Made sure that MTUs are the same,
Disabled IPv6 in both the network manager and used browsers,
Deactivated my network keys,
DMZed my computer,
Used other DNS like Google and OpenDNS,
Checked that no firewall was running my computer ...

And it's the same result. I even tried to reinstall Ubuntu a couple of times, but no luck.

The most annoying thing about it is I can't access wordpress.org! So, there's no way it could be an ISP restriction of some kind.

When I use a VPN, I can access pretty much anything.

I'm really frustrated because I have to use wordpress.org very often.

Any clue?
