HP A6600 experiences
If anyone has any experiences they'd be willing to share, or even lab reports, on HP A6600, it would be helpful. I believe this is the same product as H3C SR6600. We're being asked to look at A6604 facing our IPv4/IPv6 transit. I'd like to get some opinions before I go through effort of getting one in the lab. -cjp
Colocation providers and ACL requests
Is it common in the industry for a colocation provider, when requested to put an egress ACL facing us such as: deny udp any a.b.c.d/24 eq 80 …to refuse and tell us we must subscribe to their managed DDOS product? -cjp

It looks like this will be their final nail though. -cjp
Bluehost/Hostmonster IPv6 SMTP black hole?
Can someone from Bluehost/Hostmonster contact me off list. One of your customers has complained to me that they cannot send mail to us. We've done some testing, and it seems it works to mailservers with only A records, but breaks with mailservers with both A and . (As in, we never even see a delivery attempt.) Thanks, -cjp

Nothing works all the time forever. I can't consider Cogent even a redundant link, since I need two other upstreams to reach the Internet redundantly. -cjp

This is my eventual goal where I'm moving. (Oswego Co., NY). I'm well aware that I'm moving outside of broadband-land, and while I'm not happy about this, the pros of moving there outweighed this con. Options seem to be limited to HughesNet and dial for the moment, but things may change if I put a tower on the property. HughesNet seems to relax it's bandwidth cap between 2am and 7am, which is helpful, but still a great shift from what I'm used to at the current residence (15/2). It would be great to get neighbors in on some sort of community solution, but it will take some time to feel out where they are on this.
Ham Radio Networking (was Re: Rogers Canada using 7.0.0.0/8 for internal address space)

Good reminder that I should renumber the IPv4 portion of that network to somewhere in 44.0.0.0/8 however. What hardware/frequencies/technology are you using for these links? Repurposed commercial microwave gear? -cjp

Perhaps one could be DOD for those operators that do not carry any DOD traffic and one could be that /8 from Softbank Japan, 126/8 if I recall it correctly. People who carry DOD traffic could borrow the APNIC block. I recommend 44/8. Does it make sense that ham radio operators have routable IP address space any longer?

Power issues at SAVVIS DC3 yesterday?
We saw multiple 110V power feeds drop simultaneously yesterday at SAVVIS DC3, around 10am EDT. Anyone else have an issue, or is someone just playing with our breakers? We didn't lose any of our 208V. -cjp
Verizon local CFA sanity check
I'm writing a LOA/CFA doc for some DS1s to be delivered to us on a Verizon private OC12 ring, and I'm getting conflicting info (including from multiple people within Verizon) on how to address individual DS1s. For STS/DS3s, it's pretty obvious, just the STS number, i.e. SCID/OC12/STS/CLLI_there/CLLI_here Anyone know for certain how Verizon numbers DS1 channels on an OC on a CFA doc? For clarity, this is Verizon local, Manhattan. Thanks, -cjp

I didn't think Verizon did DS1 level xconnects directly into SONET. It's a Flashwave 4100, I'm told it has an integrated DS1 mux. (It's not on the prem here so I have to go by others' word.) I know our other Verizon customer ring that is all Cisco 15454 can deliver DS1 without external M13. -cjp
