Yesterday's Facebook outage showed yet again the fragility of the Internet's routing infrastructure. A lot has been written about various deficiencies of BGP, the Border Gateway Protocol. But all too often, the problem isn't the protocol but the people (or scripts) administering the routers. Our ISC website did suffer a couple of outages last year due to Verizon misconfiguring BGP (sadly... several times within a few days). Facebook's outage appears to be a misconfiguration as well, according to some early statements from Facebook [1].
