Coach is the only class offered on this route. Ostriches (RFC 2549) give greater bulk transfer but slower delivery, and are not recommended for metropolitan service. Carriers carry an intrinsic collision avoidance system, which increases availability (RFC 1149).
No bird carried this page. RFC 1149 and RFC 2549 are dated 1 April, and the protocol they describe has been implemented for real once, so far as the record shows: 28 April 2001 in Bergen, by the Bergen Linux User Group with the Vesta Brevdueforening pigeon club. The figures above come from that test and from the RFCs. The colo code, the distance and the clock time are real; the delivery method is not. The same network, reported honestly, is at /status.
