I recently came across an excellent draft at IETF by Job Snijders & friends. This is to address scenarios where a network might miss communication about a maintenance activity when BGP shutdown happens. Once implemented, this can potentially offer to send peer a message with up to 128 bytes with info about shutdown like “Ticket XXX: We are upgrading the router, will be back live in 1hr” etc.
It depends by appending such data to the sys notification which is part of BGP protocol.
I posted about the home network in multiple other posts in past. I recent time I switched from Microtik SXT Lite 5 to Power Beam PBE-M5-400. This gave me a jump from 16dbi to 25dbi which gives much sharper beam. I also got a harness & climbed BTS myself (after getting permission from the manager) this time to switch gear. I think I can do a better job than wasting time in finding guys from local WISPs to do it.
Talking about root DNS server’s anycast at APNIC42. YouTube here.
Saw this excellent presentation in UKNOF 34 by Peter Stevens from Mythic Beasts. Really enjoyed the challenges and fixes he shared in running an IPv6 only web hosting. A must watch for geeks :) Also, UKNOF & NLNOG both seem to have excellent content in their conferences along with professional video recording which they make available over YouTube channels.
An impressive and detailed presentation by Mr. Dave Temkin on how Netflix deploys caching nodes and challenges around them. It’s from Feb last year.
