…which is why LINX has redundancy. why some providers opt not to use it (and so failover is truncated to just the first syllable) is beyond me. Well, actually, I *do* know: cost. cf. RapidSwitch being invisible to an awful lot of the world last week while an many other providers with LINX interconnects were just fine. You get what you pay for. (The number of “backbone carriers” is largely irrelevant: it’s peering points what matter and the ability of IP networks to utilise multiple paths is predicated on there being more than one; that’s why intersite connectivity between universities probably would be maintained while many cheap and nasty hostcos go to the wall).
