go: proxy.golang.org: widespread not found: fetch timed out

I pushed an untagged commit to the github.com/scjalliance/astconf module 3 hours ago, but sum.golang.org claims that it can’t find it when requesting its pseudo-version v0.0.0-20221209034541-5c12b5578696. It returns a 404 Not Found result.

Running go list -m for the branch does list the expected commit, but takes a very long time to run:

time go list -m -json github.com/scjalliance/astconf@main
{
        "Path": "github.com/scjalliance/astconf",
        "Version": "v0.0.0-20221209034541-5c12b5578696",
        "Query": "main",

        "Origin": {

        }
}

Performing a go get for the branch returns server response: not found: fetch timed out:

go get github.com/scjalliance/astconf@main

I get a not found: fetch timed out response after waiting 58 seconds when I go here:

I don’t know if it matters, but I did perform a forced git push to the astconf repository earlier in the evening, and I renamed the branch from master to main yesterday.

I should also note that pkg.go.dev lists v0.0.0-20221209023833-cad60e1e1338 as the latest version right now, but when viewing that version specifically it also claims that it isn’t the latest version. I used the package request feature of pkg.go.dev to request the v0.0.0-20221209023833-cad60e1e1338 release earlier this evening.

I’ve been watching the GitHub Status Page and it claims all is well.

I am filing this report as directed by the FAQ on sum.golang.org, which was added in response to #42809:

Note that if someone requested the version before the tag was pushed, it may take up to 30 minutes for the mirror’s cache to expire and fresh data about the version to become available. If the version is still not available after 30 minutes, please file an issue.

I first encountered this issue while running the Go 1.19.2 tooling on windows/amd64. I updated to 1.19.4 but the issue persists. The slow response to go list -m was reproduced in a linux environment.
