1) The traffic volume only represents traffic over the shared medium and excludes traffic over dedicated fibers or wavelengths.
2) Availability is calculated excluding unavailability due to maintenance in maintenance windows.
3) Dip in traffic growth rate early 2005 was due to move of substantial dedicated VLAN customer traffic off of the shared medium to dedicated fiber wavelengths.
4) Broadcast storm in April 2005 caused unavailability of the network. Now port protection guards the shared medium from that.
5) In September 2005 the Telecity1 switch was unreachable for some time due to a port security fault, which is now solved.
6) In June 2006 the fiber link to Redbus experienced down time due to hardware failure. This link is now backed up by a second fiber.
