Understand where gettor distribution providers are blocked
We should get a better understanding of where our different gettor providers are blocked. Right now we use four different providers:
gitlab.comgithub.comarchive.orgdocs.google.com
However, some of these domains resolve to a different URL in the process of downloading the file. For example, binaries uploaded to github used to retrieved from raw.githubusercontent.com and now it redirects to github-production-release-asset-2e65be.s3.amazonaws.com.
Perhaps we can use OONI data to stay on track of when gettor becomes unavailable due to blocking these URLs?
