Re: 3rd party network monitoring
Try Hyperspin (hyperspin.com). Basic, but pretty solid.

I've looked at keynote / redalert, but oddly enough they don't seem to be able to monitor simple ICMP round-trip times - they (or at least the sales folk that I've spoken with) insist on checking the status of a TCP port or the response time of a web server. Google searches have yielded a few leads, but nothing terribly promising. Can anybody recommend a vendor for this type of service? I suppose I could always just get a bunch of VPS accounts here and there and run smokeping, but I'd really like to avoid that. - Darrell
Power issue at Telx NYC?
One of our transits is reporting a power outage at Telx in NYC tonight. Does anyone else have any reports of a power problem in that facility? We're trying to get some word from Telx now too, but they're slow to respond.
Covad issues?
Apologies for bringing this to the list, but Covad is basically a brick wall telephone and e-mail wise right now. Does anyone know of any Covad network issues, especially in the northeast US, that might be impacting customer connectivity? -- Drew Linsalata The Gotham Bus Company, Inc.

12/8 problems?
Apologies for a post of an operational nature, but is anyone else seeing problems with ATTs 12/8 block?

Richard A Steenbergen wrote: Looks like 12956 is announcing some /8s to every peer and transit. Worse still, Sprint and GX are propagating it. This is not the first time that Telefonica has leaked a lot of garbage routes with serious network impact as a result (nor is it the second or third, actually). 12.0.0.0/8 64.0.0.0/8 65.0.0.0/8 I'd say both GX and Sprint have a lot to answer for right about now. Looks like 26210 is originating the prefixes and Telefonica is happily passing them along to the world, at least some portion of which is glad to go along for the ride. Q. How does the Internet work?

Wide Outage at DSL.net

Re: who offers cheap (personal) 1U colo?
Why shouldn't an individual be able to operated a server on their DSL or cable modem connection? Because DSL and cable moden networks have evolved into lowest-cost, widest-reach service networks designed to allow anyone with $30 access to a relatively fat pipe. As a result those networks have turned into rich sources of net garbage, and most clueful network operators have taken to defending themselves against this torrent of silliness. So, I suppose that the question is not so much of one being allowed to run a server on an xDSL or cable link, but of the real world effectiveness of doing so. Why prevent people from running servers on DSL and cable modem connections, yet say they could run an identical server in a colo? Why is one unsafe, and the other is considered Ok? Nothing is 100% safe, but I'd much rather accept unrestricted traffic from a network with 1000 customers and 2 geek engineers than from a network with 1,000,000 customers and 25 engineers on staff wading through mountains of abuse reports. At least at the smaller, more geek intensive level, there is a greater ability to deal with mischief in a timely and decisive fashion. -- Drew Linsalata The Gotham Bus Company, Inc.

Anyone from NeuLeve.bizl listening?
Given that there are no phone numbers anywhere on the NeuLevel (.biz registrar) site and email to [EMAIL PROTECTED] is going unanswered, I'll ask here. If anyone has real contact info for these folks, or anyone from NeuLevel is listening, please drop me a note off-list. A cracker/spammer has decided to list one of our customer servers as a secondary nameserver for a bunch of spam domains and we're getting hammered with spam complaints that really have nothing to with us.

Re: DS3 questions.
Drew Weaver wrote: We have a scenario where we have a DS3 at a Customer location that they want to use for both Data/PRI(voice) They need 8 Voice PRIs and they want to use the remainder of the DS3 for data. If we channelize this DS3, my question is, is it possible to use the unused portion of the DS3 as a fractional DS3, or would we have to terminate the rest as single T1s? We just went through this here. The Adtran T3SU-300 with two DSX-1 cards will do exactly what you want to do. Each DSX card peels off 4 DS-1s, leaving you with approximately 33 Mbps of bandwidth on the built-in HSSI port. Only drawback is that you need HSSI cards in the routers on both ends to handle the IP part. If you need any details or help with the setup, give me a shout.

The heart of the Internet sustained its largest and most sophisticated attack ever, starting late Monday, according to officials at key online backbone organizations. Can someone point out to me where the heart of Internet is? Oh, the heart of the Internet? Its at WorldCom headquarters, right next to the employee cafeteria. You must have missed that press release. It was the one released right after the notice officially proclaiming that UUNet is The Internet. - D
