Key Servers
I have updated the list of public key servers in my PGP pages. The
list now includes SKS servers (and a link to find more servers in
that network).
The list was updated as a result of a test I ran 4-10 September to
see how well selected servers synchronize with each other.
I generated several test keys and uploaded one to each of several
servers. I then timed how long it took each key to reach the other
servers. Then I updated each test key by adding a new user ID and
uploaded them. I timed how long it took each updated key to reach
the other servers. Finally, I revoked all the test keys, again
uploaded them, and timed how long the revocations took to reach the
other servers.
During this test, I deleted several servers from my list because
they no longer work. One server that had not been synchronizing
before now synchronizes quite well. Other servers no longer (or
still fail to) synchronize after 48 hours. I no longer list such
servers in my main list. I feel non-synchronizing servers should
be avoided and now list them separately with a warning.
One outcome of this test is that I no longer have any LDAP key
servers on my list. In particular, the LDAP keyserver.pgp.com (and
its alias certserver.pgp.com, operated by PGP Corp.) fails to
synchronize with other servers. If anyone knows of an LDAP server
that not only functions but also synchronizes with other servers,
please let me know.

How about LDAP europe.keys.pgp.com? I don't know if it synchs, but it
seems to be working properly right now (wasn't several days ago when I
last checked it).

europe.keys.pgp.com is not synchronizing well. More than 5 days
after I uploaded my test keys, it has only two of the seven I
uploaded to other servers. Neither of my two test keys on
europe.keys.pgp.com are revoked, more than 10 hours after I
uploaded the revocations, again to other servers.
europe.keys.pgp.com is actually an alias for horowitz.surfnet.nl,
which was the only LDAP server I had on the list in my PGP
options. This was my most preferred server and was to be part of
my test. Before I uploaded its test key, however, I deleted
horowitz.surfnet.nl from my PGP options and from my list on my Web
page when it would not return any keys (even my "real" keys, which
it had for almost three years). While it now returns my "real"
keys, it still is not properly synchronizing. If someone later
determines that horowitz.surfnet.nl is working correctly and
synchronizing promptly, I will return it to the list on my Web page
(after I personally test it).
I noticed that other aliases of horowitz.surfnet.nl are now aliases
of minsky.surfnet.nl. These are keys.pgpi.net, pgp.surfnet.nl, and
wwwkeys.nl.pgp.net. However, minsky.surfnet.nl does not seem to
accept the LDAP protocol. The test key I planned to use for
horowitz.surfnet.nl I instead used for minsky.surfnet.nl.
One of the seven test keys was uploaded non-synchronizing
keyserver.pgp.com. When it failed to propagate to other servers
after 48 hours, I revoked it on keyserver.pgp.com. An eighth
server -- nicpgp1.nic.ad.jp -- was to have also been tested; this
one seems dead now. Other servers on my Web page that have test
dates in the range 5-10 September 2004 were queried to ensure all
my test keys appeared in their correct state (new, updated, or
revoked) at the time of the query.
