But I've broken my /20 into a /21 for Ottawa, a /22 for Toronto, a /23 for
Montreal, and a /23 for expansion. I'm currently only getting transit in
Toronto, but will have a second transit provider restored in Ottawa (I was
using GT for a short while). While announcing the the /20 will my network
is reachable for single-homed Verio customers, it won't provide the true
best path that simply accepting the regional more specifics.
