Problems with WIX route servers late last week.
Hi folks This is a somewhat belated reply to those who might have noticed wiggyness with the WIX route servers late last week. Thanks to Lee from WorldExchange who first pointed out the problem. We eventually tracked it down fumble fingering at a local ISP, which caused a full route table to be sent to the route servers. As the route servers are RAM and CPU constrained, they didn't cope outstandingly well with this - while they didn't crash, they ran sufficiently slowly that other BGP sessions were getting randomly dropped. Once the offenders were tracked down and had their ways mended, it all came right. So we're currently thinking about ways to avoid this sort of DOS in future. Boxes with more headroom would be a start, so we're considering alternative hardware options at the moment. We're also considering the merits of running one RS with quagga, and one RS with OpenBGPD - that's a possibility into the future, but will require a certain amount of RPSL and looking glass rejigging before we could go live. Relatedly, Andy has been playing with alternate looking glass code, and has this under testing - the "looking glass for amiga users" (tm) http://nzix.net/cgi-bin/lg.cgi put your keyboard in the garage, click submit, and then keep clicking. Any feedback welcome. Cheers Simon
