Steve Gibbard, PCH

Steve Gibbard is Network Architect for Packet Clearing House (www.pch.net), a non-profit based in Berkeley, California. He runs an anycast DNS network which hosts the top level domains for several countries and several of the \"I\" root anycast DNS servers, maintains PCH\'s network of route collectors and route servers at exchange points around the world, and does research on the interconnection of Internet networks. In addition, Steve carries out network architecture and peering work as a consultant for several ISPs in the Bay Area and elsewhere. Steve is a former Senior Network Engineer at Cable & Wireless, and has held network engineering positions at Digital Island and World Wide Net.
Abstract: The domain name system, without which most Internet applications don\'t work, depends on reliable access to DNS information. Failure scenarios therefore exist where two Internet hosts may have connectivity to each other, but can\'t communicate because they lack a path to a DNS server in another location. A talk at last year\'s APRICOT touched on this problem in the general case. This talk will look at the DNS in greater detail, and how the placement of DNS servers for various top level domains affects their reliability in different parts of the world.
