If you are an ATLAS T2 you should have already heard about this, but
if you haven't...
Peter and I can advise on any technical points in the UK.

Dear all,
ATLAS has decided to move ahead with a rapid deployment of FroNTier
servers and Squid web caches to address the shortcomings of direct
remote access to Oracle databases holding conditions data that are
needed by jobs running worldwide. See note ATL-SOFT-INT-2009-003
(http://cdsweb.cern.ch/record/1210179/files/ATL-SOFT-INT-2009-003.pdf)
for more details.
The report of the "Analysis Model for the First Year" (AMFY) Task
Force presented at today's ATLAS plenary meeting supports this rapid
deployment; see
http://indico.cern.ch/getFile.py/access?contribId=13&sessionId=6&resId=1&materialId=slides&confId=47256
for more details.
Thanks to the development and deployment work of the BNL and other
US-ATLAS sites, and the testing done in the German cloud and at CERN
with help also from CMS experts, we now have the tools for a quick
general deployment.
It is required that every Tier-1 and Tier-2 site install a Squid server asap.
A number of Tier-1s have installed, or are going to install, a
FroNTier server; we are having, or going to have soon, direct
discussions with Tier-1 sites. A FroNTier server is also under test at
CERN, but this server will be initially reserved for further load
tests.
Preliminary instructions can be found in
https://twiki.cern.ch/twiki/bin/view/Atlas/T2SquidDeployment and the
references therein. While more FroNTier servers are installed, the
functionality of Squids can be tested immediately against the BNL
and/or FZK servers. The same wiki page is used to keep track of
installation and test progress.
In order to speed up the deployment of the Frontier/Squid system for
ATLAS, we appoint John DeStefano (BNL) and Rod Walker (LMU) as
coordinators of this activity. Within this organization, Douglas Smith
(SLAC) will be the reference person concerning Squid issues.
For general questions and hopefully answers, sites should send
messages to the database operations support list at
