Can't connect to Github only

Hi all.
A good part of this story is told in this question: http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Jquery/Q_28579617.html#a40496956

The problem is that suddenly I'm not more able to connect to the Github server: each call ends up with a timed out error. I tried to flush dns, to change the dns to google's ones, to sett all to automatic... Nothing to do.

Ping returns this:

Pinging 192.30.252.128 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 192.30.252.128:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Open in new window


whereas nslookup returns this:
Server:  google-public-dns-a.google.com
Address:  8.8.8.8
Name:    github.com
Address:  192.30.252.128

Open in new window


HTTPFox returns NS_ERROR_NET_TIMEOUT

Unfortunately, Github is a too rich resource to leave it back: does someone have any idea?
Thanks to all in advance.

Looks like your trace fails at Vodafone's network. Good news, it's not your stuff. Bad news, it may be DDOS or some other issue that may be affecting Github. Their Twitter page mentioned at least 2 DDOS attacks against them this week, so it may be recurring.

Says everything's normal, but that was two days ago.
