Hello everyone!

I had

  keyserver hkps://pgp.surf.nl

in my ~/.gnupg/gpg.conf , but I have been experiencing issues with it
for the last few days, see the following excerpt from /var/log/syslog :

  dirmngr[3569]: error accessing 'https://pgp.surf.nl:443/pks/lookup?op=3Dg=
et&options=3Dmr&search=3D0x............': http status 503

I tried to change keyserver.
The Debian wiki key signing [page] suggests the following ones (beyond
the Debian keyring one):

 * https://keyserver.ubuntu.com (recommended)
 * https://keys.openpgp.org/ (used by Thunderbird)
 * https://pgp.surf.nl/
 * https://pgp.mit.edu

[page]: <https://wiki.debian.org/Keysigning>

Among these, I only managed to make the following one work:

  keyserver hkps://pgp.mit.edu

But it seems to work unreliably, it worked for a couple of key
refreshes, but now it's giving me:

  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: command 'KS_GET' failed: No keyserver available
  dirmngr[4391]: host 'pgp.mit.edu' marked as dead
  dirmngr[4391]: command 'KS_GET' failed: No keyserver available


Which keyserver do you currently use/recommend ?

Thanks for any help you may provide!


P.S.: please Cc me on replies, I am not subscribed to the list.
