Hmmm... Perhaps the issue is not IPV6 after all (as suggested elsewhere in this thread).
Check this out:

As you can see, the request fails in the same way for both IPV6 and IPV4.
So how do I go about diagnosing this failure to access docs.raku.org?
It _does_ seem to be related to access through my Comcast router and network (access via my cloud server and via cell data both work fine). It does _not_ seem to be dependent on IPV6 vs IPV4.
