Re: BerkeleyLUG's Virtual Meetup this Sunday 2021-02-28 ... & www.berkeleylug.com

["Michael Paoli" <Michael.Paoli@cal.berkeley.edu>]

And, someone that joined, reported that www.berkeleylug.com wasn't
working, but berkeleylug.com was working fine.
Poked into it a bit and ... egad, we were missing the IPv4 address
on www.berkeleylug.com.  So, for folks lacking IPv6 it would outright
fail - anyway, added the missing - and all the authoritative
nameservers picked it up in short order.

Negative caching 'n all that - could take up to 24 to 48 hours
to be 100% effective Internet-wide.

In any case, for the web, berkeleylug.com is the canonical,
so http[s]://www.berkeleylug.com/ will redirect to https://berkeleylug.com/
(and preserving any path portion)

$ curl -I http://www.berkeleylug.com/whatever...
HTTP/1.1 301 Moved Permanently
Date: Mon, 01 Mar 2021 00:09:05 GMT
Server: Apache/2.4.38 (Debian)

$ curl -I https://www.berkeleylug.com/whatever...

And, peeking over history (RCS) and such - looks like that was missing for a
long time.  Likely got dropped at time of DNS migration off of
Google's DNS.  Checking over RCS history, it's
missing back at least as far as 2019-05-07T08:23:45+0000.
