Hi Stuart,

I can confirm this by their design and is exactly how they intended it to be, 
not an error. We've taken it to a senior account level and they have said that 
this is precisely what they mean when they say it's "Diverse Redundant"... It's 
not an error with ours, but literally everyone at any of their sites who has 
this is getting the same service as we are, I'm told.

Several other carriers (including the likes of Cogent) lost both their feeds 
too from what we saw - and I can't imagine they were expecting it to be this 
way either.

Thankfully our core kit had locally installed UPS systems of ours (on both 
feeds) so customer-impact was minimal, but even so, 25 minutes was very close 
to their runtime limits! Should I really have to waste large spaces in our 
racks with our own UPS systems in a facility where I'm paying for the 
resilience already? I don't believe so myself. Maybe we will drop them all to 
single feeds and increase our battery capacities...

Cheers,

Sounds pretty weird that an operator of that scale would be doing that as 
common practice.

Could it just be a simple case of them giving you two distro's off a single 
feed by mistake? Are you able to talk to someone actually on the ground in ops 
at the DC about it or do they just defer you to "procedures"?
