Per TFA > More importantly for SourceHut, the proxy will regularly fetch Go packages from their source repository to check for updates – independent of any user requests, such as running go get. These requests take the form of a complete git clone of the source repository, which is the most expensive kind of request for git.sr.ht to service. Additionally, these requests originate from many servers which do not coordinate with each other to reduce their workload. The frequency of these requests can be as high as ~2,500 per hour, often batched with up to a dozen clones at once, and are generally highly redundant: a single git repository can be fetched over 100 times per hour.
