What I have seen lately with telco's building and operating Metro Ethernet =
Forum (MEF) based Ethernet networks is that relatively inexperienced telco =
staff are in charge of configuring and operating the networks, where telco =
operational staff are unaware of layer 2 Ethernet network nuances, nuances =
that in an Enterprise environment network engineers must know, or else. I h=
ave seen numerous instances of telco MEF layer 2 outages of 20-30 seconds w=
here my layer 3 routing keep-alives time out. Subsequent telco root cause a=
nalysis has determined that spanning tree convergence brought down multiple=
links in the telco MEF network. One telco technician, assigned to Ethernet=
switch configuration, told me that a 20-30 second network hang is not real=
ly a big deal.

Nope. But if this same issue crops up again we'll have to "work the system"=
harder and demand calls with knowledgeable people; not an easy task for a =
customer my size (I'm not Starbucks with thousands of sites). A single outa=
ge can be understood, seeing repeated issues means I want to know what's go=
ing wrong. If the issue is something simply mitigated and the service provi=
der hasn't taken steps, I need to start looking for a different service pro=
vider. Everything has a little downtime every now and again and I can live =
with it on lower speed circuits.

To determine whether its an honest mistake or a more systemic issue that sh=
ould push me toward another option.
