As to railroad right-of-ways, they will only let you within 30 feet of the tracks, which is still in the ror. It is safer than anywhere else because of the difficulty of getting permits to dig in railroad ror (5+ years here in Washington) even for other utilities. Some idiot with a backhoe can still be way of target though and get you. Derailments and floods are also big problems in rr-ror. The only real protection you have is ringed SONET, however, even in that arrangment some carriers do not have the ability to reroute everything, just the priority stuff. So they'll still have outages. It's all a matter of capacity and what electronics they use. <lurking mode off> Previously, the telephony industry has had a surplus of fiber. But since the Internet has taken off, much of that excess has been taken by dedicated Internet customers, and expanding POP sites. Now, many facilities-based carriers are having to lay new fiber to meet the unending demand. Perhaps the fiber cuts we are seeing are more often related to construction of this new fiber, and not freak accidents (farmer joe and his shovel). If so, then no matter where you run the fiber, if it sits next to existing fiber run, you run the risk of new construction accidents. In effect, the backhoe in the above example will be "targeting" the fiber already in the ground. -Brian brian(a)mail.usld.net @USLD Internet Services The views come from me and are mine, not USLD's. <lurking mode on>

Marketing depts. throughout the industry have used it and all come > up with their own definition to suit their network No kidding. I once encountered a hole-in-the-wall provider in Seattle that claimed to be "Tier 1." When I disagreed he had the gall to tell me that he was an Internet guru and had originally coined the term "Tier X." So much for truth in marketing. Unless a user is trying to do cross-country VPN, a good regional multi-homed provider has the best performance, quality and service IMHO. Matt

So, when getting capacity make sure that it is provisioned over 1+1 sonmet and thet the local loop also is redundant and thet you get a primary and protect router. --Peter

It's not always the equipment operator. I was witness to a ConTel fiber cut along Route 66 aboard MCLB Barstow. The fiber was cut by, get this, a road grader. The fiber was buried (if you could call it that) along the shoulder of the road (which sloped upward about three feet), three feet from the edge of the road, _at road level_! It was also over 6 feet out of alignment with the orange markers. In the process of widening the road, the grader caught the conduit and broke it, along with the fiber. The operator didn't even know he did it until the ConTel crew showed up. Crude ASCII art of where the fiber was buried (in profile): ----------- / _______________/ X <------- Fiber ^ | Road This cut supposedly (according to the ConTel repair crew) killed phone service, including 911, for 120 square miles of eastern California. I heard that they went to a SONET ring shortly after this incident..... -- Eric Kozowski VP Internet Services eric(a)structured.net Structured Network Systems, Inc.

IP and DNS management system
by Rick H. Wesson 17 Jul '97

17 Jul '97

Forgive me for my non-opperational post ;-) I'm working on a IP management system. It stores the addresses in a MySQL database (could also work with oracle) and a command line interface for allocating IPv4 addresses. Conseptually its like the tree program by Charley Kline. Its written in Java and uses JDBC. If this sounds like something folks might be interested in drop me a note and I'll send you a copy of the source once I get it to beta. Oh, I've got something simular for DNS and am thinking about making them work togther ;-) This software is GPLed, its free. If you are interested in things like these drop me a note and tell me features you would like to have. -Rick =================================================================== Rick H.
