SonarCloud resource rate limiting?

On days that I work from home, it seems that my download speeds from SonarCloud for plugins/jars is abysmal. I think I’ve been rate limited by SonarCloud.

Here’s what I mean. When I start the sonar scanner from home, it starts to download all plugins that are out of date. However, I can never get beyond downloading the first plugin.

08:41:07.900 DEBUG: Get bootstrap index...
08:41:07.900 DEBUG: Download:
08:41:08.883 DEBUG: Get bootstrap completed
08:41:08.890 DEBUG: Download to /Users/username/.sonar/cache/_tmp/fileCache4676574325080853549.tmp

I can see it downloading (slowly) in the tmp folder, but it’s something like 12 KB/s… which usually times out, or takes 30 minutes for each plugin.

  • This has been happening for the last week or so? But maybe it’s been going on longer than I’ve noticed.
  • When I’m at work on a different IP, it downloads the 15MB file (and all other plugins) instantly.
  • I’ve checked my network connections against other endpoints and they seem to be fine. It’s only the SonarCloud files/plugins that are slow to download.
  • Over cellular, it works fine.
  • My ISP won’t assign a new IP address, so I’m out of luck there.

Is there a possible rate limit happening from SonarCloud to my WAN? Or something else that I can do to resolve this issue?

Hi @Kyle,

No we don’t have rate limits in place on the SonarCloud side.
I was able to test I get stable and fast download rates from the same IP, downloading the scanner jar (x1,000 times). The bottleneck must be elsewhere!

Any suggestions on how to debug this? It always works great except on my home network.

You may have a go through a VPN to see if that changes anything. Otherwise, you may want to check with your ISP.

The issue seems to have self-resolved itself? I’m not sure why it was so slow for a week…


I’d close if I could.
