Very slow clones for the last 3 weeks, 3Kbs

[mangelozzi]

Firstly, you can see, my connection is fine, 48Mbs down, 47Mbs up. This is a speed test running while peforming a git clone:

And heres the very slow clone (3Kbs) , tried 3 times to checkout 25MB repo, took over an hour to checkout 12MB (used --depth=3).

Using github debug (https://github-debug.com/):
It says post the results in support, and this category seemed like the best fit, so I don't know if its in the right place, but here the results:

I'm having this same problem! If the repo is large enough, it literally never completes the download. Your internet is faster than mine but I have a similar line as your ??? line where 100% of the packets are lost for some reason.

[jdevfullstack]

is this fixed by now ?

[airtower-luna]

It says post the results in support, and this category seemed like the best fit, so I don't know if its in the right place, but here the results:

This isn't support, this is the community forum. To reach GitHub support, use their support form: https://support.github.com/request

Another option (both is good!) is to contact your ISP and ask why their route to GitHub is slow.

[iAliJ]

This post came up on google when I was searching for solution, using a VPN helped me, as mentioned above me it seem like an ISP routing issue. I used to Max 1Mib/s then drops to 200 Kib/s after using a VPN the download is stable at 9 Mib/s

[ell1e]

Not sure if this is related, but GitHub's HTTPS clone server handling seems to generally have some networking config issues: https://github.com/orgs/community/discussions/135808 (while e.g. the regular site HTTPS downloads that don't go through the git backend directly are fine)

[adi518]

I tried cloning with both HTTPS and SSH and both are super slow to download. Sometimes it'd even drop the connection.

[ibizoobysa]

I’ve totally been there with the painfully slow clone speeds, and it’s super frustrating. For me, using a VPN made a huge difference—my speed went from a snail's pace to something much better. Turns out it was an ISP issue, just like others have pointed out.

[ell1e]

If your connection is slow enough, there also seems to be a GitHub-side issue on top, sadly. It seems to use too short timeouts where a progressing but slow git clone can get shot down. At least that's my best guess for what's going on.
