Git repository is extremely slow (impossible to clone) #51359

System Information
Windows 10 / Radeon RX 460

Blender Version
Latest at git://git.blender.org/blender.git

Cloning from
Florianopolis, Brazil

The repository is extremely slow, being impossible to clone for a couple days now. I've cloned other repositories at normal speed, so I'm sure this is not some configuration at my end, besides, I've checked firewall and antivirus for the chance something might be blocking traffic, but nope. I'm unable to clone into Blender's repository due to extreme slowness. I've cloned blender.git several times in the past without any problems so I don't know what's going on...

The repo seems fine ( I'm cloning from canada at +- 1.77 MiB/s ) ,maybe it's a local routing issue?

@LazyDodo mmm, I see! :// Well, I don't know what to do, does traceroute info help? Here's my report: (Except I can't read it! hehehe)

One tip is to see if this only happens during particular times of the day. For instance, for years, the SVN/tracker/wiki sites were all slow from about 0200 UTC to 0600 UTC (or some subset of that) as the daily backups were running at those times. Of course, this may not be a factor here - I personally haven't seen it happen with the git server. Then again, I haven't had time to update in a while either ;)

@PedroRubini Looks like your problems start showing up when your packets hit spain and get some crazy latency. Unfortunately, we don't have control over the routing of our netblock. It is (generously) sponsored bandwidth from XS4ALL, and tends to get a lower priority and bandwidth limits once it leaves Amsterdam. Traffic to the Americas can even be 15MB/sec while EU is 80MB/sec+, for example. There is simply nothing we can do about this types of problems.

Also keep in mind that server load could possibly affect such things, but that is beyond the scope of a bug report. Thanks for the heads up, but I must close this report if it is just network lag from one user.

Mmm, oh well. Are the repositories served by the same server where the binaries are served? Because I can download the binaries at normal speed... I guess to make sure this isn't just me I'd need to find a few more South Americans to see if they're having the same issue... Today I reinstalled Windows and then I tried another shot at cloning the repo but, same thing, too slow to be cloned... Maybe there's a bandwidth limit was reached? Idk, I've no idea who takes care of this! Hehehe...
