I also understand the DDEC failed which caused major routing instability. But take it with a mine of salt. Tuc/TBOH
Do I or RR need dns clue?
Hi, Mail to RR users is getting refused due to PTR issues. I contacted RR and explained that yea, one of our 2 DNS servers for the IN-ADDR.ARPA is down, but the other is fine. They said that I should either get the DNS server back up (Which of course is already being worked on, was the minute it went down) or delete it from ARIN IN-ADDR.ARPA records. Isn't the whole point of multiple DNS servers that if one is down the other can still answer queries? Or am I missing something here??? Thanks, Tuc/TBOH

If you have 2, then it depends on your setup. I prefer to always take full routes from upstreams, as long as there are good communities within that feed. This way I can vary what I accept or don't accept without the need to constantly contact the upstream. If not, then I have to fiddle more on my end, but I always keep the control. I personally run 2 routers (Ok, switches with routing code, so my memory footprint is severely limited) each with a link to a provider. I ask for full routes PLUS default route. Internally, I discard /24's on both links, and pref up the communities like customer and send them over to the other router with the default route. Saves me alot of memory, plus gives me alot of control. Tuc/TBOH ___ NANOG mailing list NANOG@nanog.org http://mailman.nanog.org/mailman/listinfo/nanog

But it seems that CERF NET route-server isn't quite authoritative: route-server>sho ip bgp 204.107.90.128 % Network not in table route-server>sho ip bgp route-server> 2) The other route-server it wasn't showing up in is my "backup" provider. I'm trying to get clarification, but I think my backup provider relies too heavily on my primary provider. So yea, it would make sense, if Level3 had an issue, that the provider USING L3 would have an issue. 3) I've gotten zip from L3 about any of this. Can anyone atleast, once again, despite a certain list members contentions, tell me I'm not crazy. That someone else SOMEWHERE saw it? (Or more DIDN'T see RR. :) ) Thanks, Tuc

That way we see whats actually going over the copper and can tell that way. It costs us more, we do have a bit of an issue putting plugs on it, but in the long run its definitely worth it. Otherwise, our old system was : Black - Infrastructure/critical Green - Colocation/Customer White - KVM Blue - X-connect (Later changed to Orange when we went full fiber) Yellow- Someone threw a spare patch cord up and didn't custom create/ cut it and if I find them I'm gonna create/cut them something! White+Red spot or stripe - The junior guy was cutting KVM cables again, expect a health benefit claim later in the day. We also used the ID zip ties on each end if it was an X-over with "X-over" written on it. All plugs had boots too. Tuc/TBOH (Insert ;) as needed... ;) )

MetroOptical - Anyone know of them?
Hi Guys, We saw them (metrooptical.com) mentioned in Capacity Magazine, but trying to do any other investigation ends up flat. Website hosted at Godaddy, NIC records give a PO Box (So does the website), etc. Anyone know anything about them? Offlists appreciated. Tuc
DDOS - How much is "too much"?
Hi, I have a client who prior to me settled into a non-carrier-neutral facility. They were approached this week for "DoS/DDoS protection" which they could buy in X Mb/s, 2xX Mb/s or 4xX Mb/s scrubbing solutions. Maybe I've been out of the running my larger Managed Server Hosting Company too long, but wasn't the "non-elegant" solutions something ISPs just "did"? Was it only DoS, and when it comes to DDoS they tell you its just too much to handle. And blocking how many netblocks does an ISP consider "too many" before it tells the client there is only so much it can do for them? Do people tell/give clients their own solutions? (Like Zebra boxes that'll inject BGP into their site) They wanted me to come up with 3 reasons FOR the service, 3 against, and what I felt was a fair market value for this. I just need to know if people still did that type of stuff for each other or if everything costs nowadays Thanks, Tuc/TBOH
