    Hi Paul,
    
    and whoever might have gotten nervous about our (AS1853) "default-route":
    
    please calm down, there is no such beast, and we have never announced a
    default-route "at the Vienna Internet eXchange" (http://www.vix.at/).  
    Please read below my answer/explanation to Paul Donner,  the rumour is
    based on a misinterpretation ...

    As I'm not subscriber to the NANOG list, my CC to this list will most
    probably bounce back, therefore, Paul, please forward my answer there !!!
    
    Regards
    CP

    Dear Paul Donner,
    
    thanks for your hint.  However, we are NOT announcing a default route
    "at VIX".  AS1853 (ACOnet Backbone) is announcing a default route to
    AS1120 (ACOnet/VIX Service AS).  The router Service.ACO.net/AS1120 is
    offering access to some special servers/services for all VIX members and
    is open to peer with all VIX members.  Also the "VIX Looking Glass" is
    asking this router, which, besides of its VIX peerings, does not have
    any (not to speak about full) explicit routing information but a default
    route to the ACOnet Backbone (AS1853).  This default route is NOT
    re-advertised to any VIX peer !
    
    This looking glass wrt routing table therefore has only local meaning
    for VIX members and their customers.  We might think of placing an
    explicit note there explaining the situation.
    
    Thanks for your input anyway !
    Regards
    CP
