Sky blocking traffic to bitbucket

sedur — Wed, 15 Apr 2026 09:57:49 GMT

I have found that Sky appear to be blocking SSH communications to Bitbucket.org.
The workaround is to use a VPN service, which immediately resolved the slow/broken/blocked traffic I was seeing when attempting to use git pull/push/fetch via an SSH connection.
Using the traceroute feature, it appears that the blocking is at point 14, which is way after my sky router.
I also received lots of messages about 'broken pipe' and 'blocked by administration'.

What I found particularly confusing is that at the time I was experiencing the connectivity issues, the service was not blocked for communications to github.

Either way, it is difficult to believe that the fault is with bitbucket, when usign a VPN allowed traffic to flow normally once more.
This is very dissapointing if Sky have chosen to block or throttle traffic in this way.

@sedur not blocked for my Sky connection. Most likely cause is the setting for Sky Broadband Shield which you can control see https://www.sky.com/help/articles/sky-broadband-shield-start

As a general rule only sites subject to a UK court order will be blocked if Sky started doing otherwise Ofcom wiuld come knocking.

I'm also experiencing similar issues pushing and pulling from bitbucket. Its intermittent in that largely it doesn't work failing with "client_loop: send disconnect: Broken pipe" type errors but will occasionally succeed.

As reported by @sedur connecting to a VPN immedietely resolved the issue which indicates the problem relates to the way my Sky ISP is processing the traffic.

Access over Secure SHell would be different to the website resolving though, and not testable without Bitbucket account credentials.

@sedur @CurtisG @thmnrtn

Almost certainly something which will need to be addressed by Sky netops: chances are the contact centre people won't have any notion what that is.

Yep, exact same issue on my end

Thanks @TimmyBGood!
Any ideas how this gets progressed to Sky Netops?
I assume I need to go back to the callcentre and try to get them to evelvate

Same issue here since the past week, anyone had any luck with getting this resolved with sky?

@sedur I've got a work around for bitbucket using alternate ssh host altssh.bitbucket.org:443

Just update your ~/.ssh/config with the following

Host bitbucket.org Hostname altssh.bitbucket.org Port 443

Same here - thought i was going insane while trying to reconfigure my mac's networking settings to get to the bottom of it

Probably works 1/20 times, but as most projects have sub-modules thats blocking every git pull/push for me.

The altssh fix seemed to work with command-line git, but GitKraken (configured to use command-line git) doesnt seem like it (or at least not when using submodules) 😞

Got broadband shield disabled on my connection so it's not that.

Looks like i'm hot-spotting off my mobile phone for the time being then 😭

@sedur @FBZ @joeprisk @CurtisG @thmnrtn

I've put a request into the Superuser forum to ask if our Sky staff contacts there could draw the issue to the attention of Network Operations directly: this is in the hope it means you don't have to try and explain the situation to frontline 'support' which I think we can reasonably anticipate wouldn't be entirely straightforward ; )

Thanks Joe, I'll try this tomorrow

Same issue here! Kept getting the "client_loop: send disconnect: Broken pipe" on my Sky wifi but was working on mobile data.

I've just tried @joeprisk fix and it seems to consistently be working now. Thanks Joe!

I went through this with Atlassian support and they were confident problem was Sky side.

Workaround from @joeprisk works well.

glad I found this. I'm still experiencing the same today.

My pushes eventually work after trying about 3-4 times.

Thanks for this - I've been stumped all week and retrying endlessly.

@KevNewMedia

seems to be better now, working without override.

Any chance of a post-incident review - blocking a pretty standard business service gives me concerns if I'm honest.

Thank you for the quick reply and confirming that it's working for you @ExtraNerdy!

I'm afraid we aren't able to share that information.
