Rogers Outage Canada

Mon Jul 11 15:58:21 UTC 2022

It's hard to believe that a same time maintenance affecting so many 
devices in the core network could be approved. Core networks are build 
with redundancy, so that failures can't completely destroy the whole 
network. If it would be just "particular devices" they could be isolated 
much faster. In this case the outage was so huge that it affected mostly 
all network gear, maybe all devices from one vendor. And even after most 
of the services restored we still observed partial connectivity in some 
areas that means the impact was mush deeper, in some places down to 
access layer.

Kind regards,
Andrey
