Five 9's SLA equates to 5 minutes a year. That would be pretty tough to live up to without redundancy built in to the circuits and access devices.

Subject: OT: WAN LAN SLA Statistics
Does anyone have any details regarding industry standard SLA percentages
for WAN and LAN devices/circuits. It seems that everyone wants 99.999%
uptime but that seems rare. I am trying to find some statistics and
guidelines on more realistic figures. Any ideas on what should be an
acceptable figure???
Thanks,
Jim Fitzpatrick
