• Repeated bandwidth upgrades increase costs yet
  fail to permanently increase performance
• Surges from recreational traffic cause urgent,
  interactive business applications like EPR access
  to struggle
• Enthusiasm for VoIP (Voice over Internet
  Protocol) fades when callers routinely face
  stutter and static during peak network usage
• Intranet applications at a main data center offer
  easy access but poor performance
