Odd. Considering the default of 'gpg --detach-sign' is a .sig file.
If you do 'gpg --armor --detach-sign' then you get a .asc file, which is
a base-64 encoded version of the regular .sig. (Or something to change
it from a binary file into an ascii safe file)

I get the same complaint about 'Unable to download', though. So we
certainly need to fix it somehow. I'm including some people who might
have access to be able to change the server configuration.

I would assume it is on the "standard" servers of 'subkeys.pgp.net' and
'pgp.mit.edu'.

gpg --keyserver subkeys.pgp.net --recv-key A0B3E88B

Works fine for me.

It might be just that subkeys.pgp.net and pgp.mit.edu don't like to do a
"search" on the key id. They prefer it if you use '--recv-key' to
'--search-keys'.

I updated your hint a bit. I think subkeys.pgp.net is a more official
location.
