I have never used those "56K" dial-up modems because they are asymmetric: it's only "56K" in the downstream direction, and I oppose that on principle. Prior to switching to my current 384 kbps SDSL (served by a V.35 CPE device of my own design and make, see earlier messages in this thread), I was using an always-on (immediate redial on disconnect) analog modem connection at 31200 bps. One of the 4.3BSD-Quasijarus MicroVAXen acted as the router, and the PPP implementation in the kernel was written by me from scratch: the original non-Quasijarus 4.3BSD only had SLIP. MS

The CPE vendor that finds a hack that lets the LAN carry on working while the WAN goes away and manages to slap the "With Home Network Resilience!" label on the box correctly will presumably do quite nicely out of it. For this kind of site, I can't see what is *actually* going to break if the CPE keeps sending RAs for the prefix beyond the valid lifetime while the WAN is down. As long as it advertises a short valid lifetime itself, such that if the real prefix changes[0] when the WAN comes back up it can renumber everything on the LAN quickly, it looks a lot like a "Just Works" scenario to me... Regards, Tim. [0] Which it won't, of course, because residential users are going to get proper static connections by default, rather than another round of "business class" price-gouging :)

Forgot to add: this thin coax Ethernet interconnects several MicroVAXen (including ivan.Harhan.ORG, the machine on which my mail lives and from which I am sending this post) running 4.3BSD-Quasijarus, and a Cisco 2500 router which connects my retrocomputing centre to ARPANET^H^H^H^H^H^H^HSDSL. The SDSL connection is made via a device of my very own design and make that connects to the copper pair, handles the physics of 2-wire full-duplex transmission, and converts SDSL/ATM to V.35, or more precisely EIA-530, which then goes to the Cisco 2500.

Just in case it isn't clear, I use all of my ancient computing and network technology by a *very* deliberate choice. Just take the case of the hardware gadget I've designed and built myself that goes from SDSL/ATM to V.35-nee-EIA-530: I've only built and deployed it in the summer of this year, although I had wanted one since late 2004 and had been developing it as a hobby open source hardware project since 2006.

Root Zone DNSSEC KSK Ceremony 3 Completed
by Joe Abley 02 Nov '10

02 Nov '10

KSK CEREMONY 3 The third KSK ceremony for the root zone took place in Culpeper, VA, USA on Monday 2010-11-01. The Ceremony Administrator was Mehmet Akcin. The ceremony was completed successfully. Video from Ceremony 3 was recorded for audit purposes. Video and associated audit materials will be published in 1 to 2 weeks, and will be available as usual by following the "KSK Ceremony Materials" link at <https://www.iana.org/dnssec/>. Ceremony 3 included processing of a Key Signing Request (KSR) generated by VeriSign, and the resulting Signed Key Response (SKR) contained signatures for Q1 2011, for use in the root zone between 2011-01-01 and 2011-02-28. CONTACT INFORMATION We'd like to hear from you. If you have feedback for us, please send it to rootsign(a)icann.org.

Yep, that's the hack I was getting at. As a non-technical end-user, once my CPE has got a prefix from my ISP and advertised it to the devices on my LAN, the same prefix should keep working until: -my ISP assigns a different one -the end of time whichever comes first :) Having my PC not be able to talk to my printer any more because my DSL / cable / wimax / whatever has been down for "too long" is not acceptable.

OK, sorry, I think we're addressing different points of the same comment. I was looking very much at the second half of "all residential users get PI so that if their ISP disappears their network doesn't break", ie the reason *why* they'd want PI. I assumed that was "disappears" as in "has an outage", rather than goes bust, user changes ISP etc - and if you've only got one ISP, you don't need PI or ULA to have *local* connectivity work through an ISP outage. I agree, on the current routing platforms we have, PI for every end site is insanity. Whether we should be looking for routing platforms (or a different architecture - LISP?) that allows PI for every end user is a different question... Regards, Tim.
