Though that's true, the SIX has been extremely reliable: one unscheduled
core outage in the last 3 years (about 30 minutes due to power loss). In
one other case, an extension switch (7 peers) was disconnected for about 30
minutes to troubleshoot a potential problem.
Peer-operated extension switches have also been very reliable. Most
are above 99.9% availability including scheduled maintenance and 99.99% for
unscheduled problems.
The SIX's staffed 24x7 NOC lets peers treat it like any other carrier
relationship, with one phone number to report a problem. Often the ops
staff at national networks never know the SIX is non-profit or
donation-supported.
Peers of all sizes seem happy with the reliability. Everyone has
open-posting mailing lists and an annual opportunity to elect the Board of
Directors, so there is recourse if circumstances change.
Cheers,
Troy
