  requests

  10GB/sec connectivity to the National Lambda
  Rail.
• The NLR POP in Baton Rouge has not been affected
  (the route runs from Baton Rouge to Houston).
• The core routers will be delivered to each
  campus as soon as they are ready.
• The awarding of the local loops seems to be the
  bottleneck with all of the purchasing/bid
  requirements.
• HSC-NO data center is located at the Public
  Safety office (BR?)
• Tulane data center is located in Houston.
• UNO data center is at LSU.

Status of CAPS Site

• Caps Mostly recovered from (premature)
  installation sam v6 products. Had to retailor
• all samgrid products. Had issue (again) with
  disks declared as INACTIVE.
• Problem had to do with mixed case nature of
  domain name(Latech.edu vice latech.edu)
• Found workaround to this problem by digging into
  the Samshifter FAQ's.
• At present I am about finished getting an upgrade
  to condor installed on all machines (windys
  still not done).
• Also recovering from loss of an /apps/ disk

Status of SuperMike Site

  station and gatekeeper combined.
• Installed an additional 200 G on this machine
  last month.
