*** Site news and issues: ***

BNL:
- No updates

CERN:
- Manual debugging of broken maintenance scripts
- Made request at WLCG T1 meeting for dedicated, part-time, local resource for 
  prioritized site management
  * Will pursue this at ATLAS S&C next week

RAL:
- Frontier services are working fine
- Chasing cloud sites to follow-up on SAM reported issues
  * T3s may need local setup configuration to point to RAL Frontier
  * Degraded performance at Glasgow due to power issues
  * Also reflective of local down-times
  * Not quite as useful for testing T2 fail-over paths, but do help verify 
    T1 fail-over problems
    - Not checking every worker node
- Central reported MRTG statistics not matching up with local monitoring
  * MRTG hit rate seemed higher than local script reporting

*** Testing: ***

Geometry caching
- Vahko now testing

*** Development: ***

David: progress on ATLAS packages
- Progress has been made, but adjustments are necessary after review
  * Log rotation: locations and other debugging
  * Manual changes that will survive an RPM upgrade (file, environment 
    variables)
  * Adding a small software layer to accept manual, scripted variables
- Meeting later today with Dave

MRTG monitoring fixes for launchpads
- Added new configurations to existing scripts
- PIC not reporting stats
- Some sites reporting zero cached objects
- Currently debugging

AGIS integration
- Technical requirements sent 3/28 week to AGIS; they're looking at it now

*** A.O.B.: ***
ATLAS Software & Computing next week
