Hey all
I'm having issues where any SSH connection to github will time out on my virgin connection. I've tried multiple github accounts with different SSH keys and all the same.
Those accounts and keys all work perfect if using mobile data tethered from my phone (EE).
Even the basic SSH test ssh -T git@github.com will time out:
ssh: connect to host github.com port 22: Operation timed out
I phoned support for nearly an hour and basically no-one knows what SSH is (kinda fair) and after rounds of trying different things it's still not working...
Any ideas anyone?

Can you do a trace route?
C:\>tracert github.com

It would appear this fails too

Your github.com IP address is completely different to mine, here is what nslookup returns for VM's DNS.
C:\>nslookup github.com 194.168.4.100
Server: cache1.service.virginmedia.net
Address: 194.168.4.100
Non-authoritative answer:
Name: github.com
Address: 140.82.121.4
I use Quad9 which returns the same IP address.
C:\>nslookup github.com
Server: dns9.quad9.net
Address: 9.9.9.9
Non-authoritative answer:
Name: github.com
Address: 140.82.121.4

Virus Safe strikes again!
Doing a reverse lookup on the IP address:
C:\Users\timdu>nslookup 81.99.162.48
Server: UnKnown
Address: fe80::c206:c3ff:fe3b:cc8d
Name: lang-sspiprxy.network.virginmedia.net
Address: 81.99.162.48
Do we really want to stop users using Github? - I don't think so.

Sorry to jump on this thread but I have the same issue, except I already have WebSafe disabled and have custom DNS. github.com resolves to the correct IP but traceroute fails here:

Everything after this is just: * * *
Testing with:
ssh -vT git@github.com
This works fine on 4G but WiFi it fails.
All over SSH works, although it's definitely slower.
Any help would be appreciated as I need GitHub for work.!

traceroute is not failing, try sending ICMP Echo packets instead of the default UDP, i.e. traceroute -I github.com
