How to begin making my own ISP?
by hasserw＠hushmail.com 16 Sep '11

16 Sep '11

I want to begin making my own ISP, mainly for high speed servers and such, but also branching out to residential customers. I'm going to be in Germany for the next school year (probably either Frankfurt am Main or Berlin); any suggestions on what sort of classes I can take there that will be in English and will teach me all I need to know on how to build and manage my own ISP, AS, etc? Thanks.

routing issue for verizon dsl customers in western massachusetts
by Brian Gold 16 Sep '11

16 Sep '11

Hello all, I posted this to the tech@lopsa mailing list and was advised to repost it here. If anyone can help, I would be very happy to avoid having to deal with hours more of Verizon level 1 tech support. Over the past week, we've discovered that there is an issue with the way some Verizon DSL customers are being routed in Western Massachusetts that is preventing them from reaching my employers public IPs. The problem is only limited to Verizon DSL customers, everyone else can reach these IP addresses just fine. After many hours on the phone with Verizon tech support, I finally managed to get myself and one of my coworker's home dsl connections switched from a "redback router" to a "juniper router" which resolved the issue, but only for us. I was told that everyone else in the area that is being affected by the issue have to individually call Verizon tech support, go through the same multi-hour troubleshooting steps, and if the technician is bright enough to recognize what is going on, get their issue escalated up to the central office where (in 2-4 business days) they will be switched over to the juniper router. Obviously, this is not the ideal solution. I'd really like to make the higher ups at Verizon aware of this issue and come up with a solution for all of the affected customers, but because I only have a residential account and my employer doesn't use Verizon, I've been stymied in all of my attempts so far. Does anyone here have any contacts at Verizon that I could get in touch with?

Anyone from Covad here?

Covad (or should I say Megapath now..), You have DNS servers that are failing to resolve anything at this time: 64.105.172.26 and 64.105.172.27 are both failing. This is a Bad Thing as these are the servers that the majority of our Covad customers use. Sincerely, Bobby Glover Director of Information Services SVI Incorporated

Congratulations on your nat444 connection. I suspect a autoblocklist of sorts. They somehow always end up blocking the hosts you are using. I vaguely remember my watchguard firebox 1000 doing so. It was red too. Regards and good luck, Seth typed on a tiny touchscreen, why exactly?
