Bluffing
• ~ 150k page views per day

• Varnish helped even more
• ~80% cache hit rate
• CacheSetup makes it possible

Source Control
• Subversion
• Synchronised to svn-mirror.plone.org
• Access control via LDAP
• Reporting to CIA and mailing lists

Who are you ?

• Duplication is evil
• Single account database

LDAP everywhere

LDAP setup
• OpenLDAP everywhere
• PloneLDAP is your friend
• Apache is your fiend

No Worries Mate
• Spam on dev.plone.org
• Spam on lists.plone.org
• Spam on paste.plone.org
• Postgres and Varnish stability
• Robots are coming to get us

Pain pill

Dreams ...
• Plone 3.0 for plone.org and plone.net
• Redundancy
• Single sign-on
