E.g., a Level3 outage might affect 30% of the user population, and we have 50,000 users in the user population, and service was down for 90 minutes, then that's 0.3 * 50000 * 90 = 1,350,000 user minutes. So this would be a reportable outage.
> 3. Ordinary Outages
> If customers can't have working non-911 phone calls for 900,000 user-minutes or more, and it lasts at least 30 minutes, then it appears you have to report it.

> So how about a SIP trunks to Intrado or Dash that's installed for 911?
> What about a SIP trunk that's used for both ordinary calls and for 911?
> So how about those MPLS tails from Level3 or XO?
> Or how about those T1s you lease from Verizon?
> What if they have packet loss great enough to interrupt working RTP flows, but not high enough to prevent SIP registration?

I can see it now...
Carrier: "Technically, we didn't have an 11 hour outage"
Powers that be: "Can you elaborate?"
Carrier: "We're not sure 1) which carrier is to blame and 2) why they're
really at fault so at this point we can't"
Powers that be: "Can you clarify your comment before we impose what is
now going to be a bigger fine on your business?"
Carrier: "We have multi-homed redundancy from 6 upstream carriers and
all were available however, some rebels without a cause using silly
masks were DDoSing DNS servers"
Powers that be: "What is DDoSing?"
Carrier: "They were overwhelming the services enough so that individuals
placing real requests were denied legitimate access"
Powers that be: "What is a DNS server"
Carrier: "DNS servers resolve names to IPs. Our customers weren't able
to get to www.MyVoIPIsBetterThanYours.biz but they were able to get to
our address at 20x.xxx.xxx.xxx"
Powers that be: "Who's responsible for the DNS server"
Geeks at the Carrier: "Dan Kaminski!"
