[manual-of-style] What do we do with dead links?

[koalie]

Section 11.2 Spelling recommends:

[...] and the Excalibur home page [EXCAL] for Mac OS.

But the Excal link is dead.
I found https://download.cnet.com/excalibur/3000-2079_4-10000867.html which says "Last updated on April 6, 2020".

Should I simply update both the section 11.2 and References section by creating the appropriate entry and removing the EXCAL one?
