From james_r@jump.org.uk Wed Sep 29 11:05:45 2010 Date: Wed, 29 Sep 2010 11:05:45 +0100 (BST) From: James A. T. Rice To: members@lonap.net Subject: AS8943 disconnecting LONAP at months' end Hi Folks, After 12 years at LONAP, AS8943 / Jump Networks Ltd will be leaving, this is due to capacity concerns with the intersite links. I'm a firm believer of keeping enough headroom to cater for at least any one member/customer doing something unexpected with the capacity given them. LONAP now has a growing set of customers connected at 10GE through 40GE in various sites, yet only single 10GE links between each site. Expecting traffic mixes not to change significantly is something ISPs with customer access links smaller than their backbone can do, but a gamble in a scenario like LONAP, where members run BGP and traffic flows will change when members take on major new customers or paths elsewhere become unavailable. Having been part of peering@ for several networks peering at dozens of IXs across europe, as well as 'the technical guy' at LONAP for several years, I'm sure that IXs do not normally require members to seek their permission before using the full capacity of their port, nor do networks expect to have to negotiate with IXs before using the full capacity of their port in any given way. Apologies to any of you who have been offended at me expressing my concerns. We do value peering with everyone at LONAP, if anyone is near TFM1, TFM4, or TFM8 in Telehouse, we'd be happy to establish private peering with you, additionally our GigE connection to the LINX Extreme LAN will be active by Friday, and we're been peering at GigE on the LINX Brocade LAN for some time, we'd welcome any additional peering there: AS Number: AS8943 (RIPE) Announcing: AS-JUMP (RIPE) LINX Brocade LAN: 195.66.224.34 / 2001:7F8:4::22EF:1 (GigE) Full details at: http://www.jump.net.uk/peering If LONAP fixes their intersite capacity, and brings back the interswitch link graph visibility to members, and preferably also the member port allocations table visibility to members - i.e. achieving the same transparency as LINX, we'd be delighted to rejoin. For now, so long - and thanks for all the fish :-) Best wishes James Rice -- James A. T. Rice Director, Jump Networks Ltd
