 Thank you Pete for your assistance and fantastic program
skills. javAPRSSrvr has sure made it easy for Tier 2 to
expand globally and make the APRS-IS a better place.
 Everything should be completely back to normal. The error
has been corrected and I'm sorry if it caused any problems
or interruptions to the service we provide.

Tier 2 now has a set of 4 Hub servers located in data
centers globally. Instead of 54 connecting directly to the
existing APRS-IS Core servers, they use 4 Hubs. This type 
of distribution has improved reliability, service and puts less 
 strain on our upstream connects for over 2400 end-users.
That's 70% of all clients on the APRS-IS.
Tier 2 (aprs2.net) provides service to over 2400 APRS-IS
clients globally. This change was implemented around mid-
August and finalized yesterday. Only T2 servers have access
to these Hubs. The existing Core servers do allow end-user
connects which has been problematic. Hopefully common
sense will prevail and end-users will migrate to the T2 servers.
APRS activity continues steady growth on the Internet.
 All Tier 2 servers use the latest version of javAPRSSrvr and
each T2 sysop is a ham volunteer, who donates time and
resources FREE.
