Steve,
It should not be a requirement to have connectivity to motd.ubuntu.com to have
quick login.
Its quite common to have ingress networking like we see in our labs.
I suggest the fix would be better to background the download and to
atomically move it the content into place. Then the reader would just
display it if it were present.
Then,
a.) pure failure to reach (ECONNREFUSED or EHOSTUNREACH) would simply show no
data in motd.
b.) hang would be gone and would simply not have data in the motd
c.) fast success would be shown on this login
d.) slower success would be shown on next login (possibly stale, which is
always going to be a possibility)

Title:
50-motd-news costs 5 seconds every login on firewalled systems
Status in base-files package in Ubuntu:
Confirmed
Bug description:
I noticed quite a long time to login to some of my systems via ssh (or scp).
Investigating lead me to find out that the '50-motd-news' file
(/etc/update-motd.d/50-motd-news) was the primary cost.
In line 108 [1] it does something like:
curl --connect-timeout "5" --max-time "5" -A "..." -o -
https://motd.ubuntu.com
The systems I'm seeing this on are in a lab and do not have access to
https://motd.ubuntu.com.
The way the lab is configured, they just end up timing out. So every scp or
ssh connection
or other path to trigger update-motd will cost 5 seconds.
