Not
unheard of… requested several new quotes in the last few
months and at least 2 included $50/mo charge for BGP.
My memory could be dodgy, but I think I recall
seeing something similar on an order form they sent us for an
upgrade (or turn-up) a few years ago. We pick them up in
Amsterdam.
That said, the fee not being explicitly on the order form does not
mean it's not being charged. If I were Cogent and really needed
the money, I wouldn't mention it on the order form, but just wrap
it into the turn-up NRC or service MRC.
That Cogent are explicitly highlighting it in an order form is to
send another message, or create an industry standard.
