Re: Facebook doesn't have a route to my ISP's (Cogeco) IPv6 space?

They should probably just rebrand to CoGeCo, but that does look kinda
silly, so, they probably won't.

https://en.wikipedia.org/wiki/Cogeco

Cogeco is an acronym for Compagnie Générale de Communication ("General Communications Company").

Both Cogent Communications and Cogeco are in pretty different market
segments (for anyone in the know), so, they each probably don't really
care about the confusion in their respective target markets.

Yikes, they should change their name rather than be mistaken for Cogent lol
