Yes and yes. I didn't state explicitly that it was a problem with my
network only because I didn't want to appear overconfident in my amateur
diagnosis and I definitely prefer the second error message to the one that
dumps a trace and prompts the filing of a bug. This:

substitute: guix substitute: error: TLS error in procedure 'handshake':
Error in the pull function.

Please report it by email to <bug-guix@gnu.org>.

is much different than this:

guix substitute: error: TLS error in procedure 'handshake': Error in the
pull function.
substitution of
/gnu/store/k1da7bv579d8gvwdrakd9l4hxswknff2-guix-module-union failed
guix pull: error: some substitutes for the outputs of derivation
`/gnu/store/k2gdq7ahjaqmdgjr9xwywqpxvzazn467-guix-e07573432.drv' failed
(usually happens due to networking issues); try `--fallback' to build
derivation from source

especially to one as new to scheme as myself. I can't say why the two
errors were different as I'm not familiar mechanically with what phases
pull goes through but I can say the first error occurred during the
beginning of the pull and the second occurred in the wrap up thing it does
towards the end.
