    There was an implicit (and sometimes contractually explicit) social
    contract associated with buying from a Tier 1 provider. That was that
    I'd pay a premium for connecting, and that everyone could reach me.

    That's never a guarantee - I've had both upstream peering games and
    more conventional network outages in the last 20 years than I can
    conveniently count. But the social contract was that I was not
    going to be bitten by my provider playing games with other
    providers.

    If I am going to be bitten by that, then I have to take additional
    mitigating measures, which includes multihoming for smaller sites
    than I used to do. That costs money. In this particular
    economic climate, if I have to tell site owners that they need
    to pay more money in connectivity, hardware, engineering, and ondoing
    administration time to multihome, they are going to tell me to make
    it up on the back end, which means that paying for Tier 1 grade
    connectivity is no longer affordable.

    Somewhere, inside Sprint, is a salesperson who understands
    this and has been trying to tell his or her coworkers.
    Apparently to no good effect...

    The recent depeerings have two effects: One, they devalue higher priced
    Tier 1 ISP connectivity because they reintroduce the political/financial
    depeering risk into overall connectivity reliability, and two, it pushes
    the boundary downwards in both small/mid tier ISPs and content sites
    where multihoming is either necessary or strongly advised. That leads
    to additional cost and engineering time, a need to shift high level industry
    effort more towards supporting new multihoming sites again (ugh, this is
    never a fun surge to deal with, as everyone finds out the things BGP
    is bad for all over again). All on top of the looming IPv6 deployment
    surge we're all facing.

    Not to be alarmist, but what the @#$#@%@#(*&$% ?
