Start of hurricane season 2000
by Sean Donelan 03 Jun '00

03 Jun '00

Have ISPs finally figured out how to keep things working during storms? June 1 is the start of the US hurricane season, and several waves of major storms passed through the midwest and northeast yesterday. The FAA and several electric companies had scores of problems, but I didn't hear about any ISP-affecting problems anywhere. Are we off to a good start?

The Cidr Report
by Tony Bates 02 Jun '00

02 Jun '00

This is an auto-generated mail on Fri Jun 2 12:00:00 PDT 2000 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

ALTDB.NET dead again (thanks Netsol!)
by Steve Rubin 02 Jun '00

02 Jun '00

ALTDB.NET is dead again due to Network Solutions once again managing to remove the records from the root servers! (Atleast they show up in the whois database this time). You might recall back in March, ALTDB.NET was removed from the database for "lack of payment". I ended up having to pay for the domain again, even though it was only a few months old. Needless to say, I am not using NetSol for anything new. If anyone from NetSol is listening.. HELP! -- Steve Rubin * ser(a)tch.org * http://www.tch.org/~ser/

(Off-topic) NETA conference added to LISA, papers wanted!
by David Williamson 01 Jun '00

01 Jun '00

Good news for network administrators! * Did you attend NETA'99 (The Conference on Network Administration) and liked what you saw? * Did you miss NETA'99 because you were too busy to attend? * Have you been wondering when the next NETA was going to happen? If you anwered yes to any of these questions, I have good news for you! The content of NETA has been added to LISA 2000! That's right! We're bundling NETA with LISA 2000. This will give network administrators a chance to attend the premier system administration conference, LISA, and exchange ideas with other IT professionals as well as have content relevant to their areas of expertise. In addition to the extrordinary LISA content, the great NETA content you'll also receive admission to the LISA 2000 Security Symposium all for one admission price. But the Network Symposium can't happen without your help. We're still looking for great papers to fill out the conference. If you work as a network administrator or do network administration as part of your job, consider writing a paper about what you do to make your day-to-day work easier. Have you written a "cool tool"? Are you doing some innovative network design? We want to hear about it. If you'd like to submit an abstract, please visit http://www.usenix.org/events/lisa2000/cfp/submit.html and fill out the form. You can always find the latest scoop on LISA 2000 at the Usenix Web site: http://www.usenix.org/events/lisa2000/. We hope to hear from you soon, and to see you at LISA in December! -David Williamson & Bill LeFebvre LISA 2000 Network Symposium co-chairs

Re: The %^? did it!
by Robert Cannon 01 Jun '00

You can learn more about the FCC's approach to IP Telephony, access charges, and the Upton Access Charge Legislation at www.cybertelecom.org The legal history behind all this goes back over 30 years and involves the FCC's Computer Inquiry proceedings. In about 1980, in the Computer II proceeding, the FCC distinquished between basic telecom service and enhanced services. Basic services, to put it simply, is where the message travels over the network transparent to the network - there is no interaction between the message and the network. With enhanced services, there is some level of interaction between the message and the network - it "employs computer processing applications that act on the format, content, protocol or similar aspects of the subscriber's transmitted information." Basic service is regulated as telephone service under title II of the Communications Act; Enhanced services are "unregulated" by the FCC. If you think of the IP stack, basic service is the physical transport layer and maybe layer 2. Enhanced services is the TCP/IP layer and above. This means that applications such as IP telephony currently fall under the category of enhanced services and are "unregulated." When the FCC was dealing with the breakup of the ATT monopoly, the question was, what would the lucrative long distance carriers pay to the expensive local loops to maintain the infrastructure. The answer was metered access charges. In this 1980s proceeding, the FCC also considered Enhanced Services Providers and decided that they would be exempt from the metered access charge. That exemption has been reaffirmed several times over the years. So, under current FCC policy, ISPs do not pay this metered access charge. The policy was based in party on the competitive, innovative, and nascent nature of the enhanced service provider market - well remember that one of those nascent enhanced service providers is in the midst of trying to buy Time Warner. As far as definitions go, the FCC has put forward a definition of IP telephony. Sec. 255 requires that telecommunications service providers and manufacturers make their equipment accessible to the disabled. In the recent 255 proceeding, the FCC affirmed that 255 does not apply to enhanced services (does not apply to ISPs). However, last fall the FCC released a Notice of Inquiry to ask what is the impact of IP telephony on the disabled community, how is industry responding, and what is the proper roll of the federal government. First, I would note that while the comment period in that proceeding is closed, you can still express your views in that proceeding pursuant to the FCC's ex parte rules (you simply have to file a summary of your comments with the FCC's secretary for inclusion in the record). I might also note that only 7 Internet parties filed comments in that proceeding the last time I checked. More info again at www.cybertelecom.org In the 255 proceeding, the FCC defined IP Telephony as follows: "Internet Protocol telephony ("Internet" or "IP" telephony) services enable real-time voice transmission using the Internet Protocol (IP), a packet-switched communications protocol. The services can be provided in two basic ways: computer-to-computer IP telephony conducted through special software and hardware at an end user's premises; or phone-to-phone IP telephony conducted through "gateways" that enable applications originating and/or terminating on the public switched network. Phone-to-phone IP telephony is provided through computer gateways that allow end users to make and receive calls using their traditional telephones. Gateways translate the circuit-switched voice signal into IP packets, and vice versa, and perform associated signalling, control, and address translation functions. The voice communications can then be transmitted along with other data on the "public" Internet, or can be routed through intranets or other private data networks for improved performance." --In the matter of the Implementation of Sections 255 and 251(a)(2) of the Communications Act of 1934, as Enacted by the Telecommunications Act of 1996, WT Docket No. 96-198, Report And Order and Further Notice Of Inquiry, 177 (September 29, 1999). A final note - The Upton Access Charge Legislation was largely passed in response to Congressman's Schnell's proposed legislation 602P to tax e-mail or tax Internet access. Of course, there is no Congressman Schnell; there is no legislation 602P; there is no such format for legislation as 602P; and there is no proposal before the US congress to tax e-mail (there is one before the UN I believe) or access. -B www.cybertelecom.org My views alone.

Provider network status update
by Sean Donelan 01 Jun '00

01 Jun '00

Some folks sent me corrections to my previous posting. Here are my updated comments. These are my opinions and not the position of my employer, my country, my planet or any other sentient being. Abovenet - Public web site with MRTG graphs, and copies of messages from their tech contact mailing list. Mailing list about problems, outages, and scheduled maintenance. AT&T - Public web site with red, yellow, green city to city matrix. Outage portion of the web site is never updated. Customer only newsgroups updated with detailed problem reports. Proactive notification for some customers with choice of media. C&W - First provider with red, yellow, green city to city traffic matric on their public web site, but you have to dig to find the problem sites. Has an outage mailing list, but never any mail and even C&W employees seem unsure of its purpose. Earthlink - Customer web site with network status. Exodus - Public web site with major trouble tickets available. Genuity/GTEI/BBN - Customer only network status web site. Public "finger" access to trouble tickets, including master tickets. Proactive notification of customers of problems with customer choice of notification media. Globalcenter - Customer only web site for dialup users only. Mailing list notification for all other customers. Mindspring - Public network status web site with current trouble tickets. PSI - used to have a detailed "finger" and public web site network status page, starting last month I get an access denied message. SBC/PBI - Public web site with current network status. Frequently updated and includes resolution or reason for outage. Sprint - Web site describes scheduled and emergency maintenance mailing lists. Only scheduled maintenance notices posted on web site, unscheduled interruptions not listed. Other people report receiving outage and maintenance notification via e-mail. Call phone number to hear network status. UUNET - web site lists scheduled maintenance activities, updated for some major outages. Says details will follow, but usually the web page returns to all systems normal message every few hours whether or not the problem is fixed. Mailing list for customers. Has a 15 minute proactive notication guarantee. Verio - Customer mailing list for outages, maintenance, and Oops messages. Web site network status page real soon.

IIRC, they had a link to subscribe on their web site. I subscribed, my sprint salesperson verified I subscribed, I also subscribed to the DALnet copy of the sprint list. No notices. No one at sprint seemed very interested in figuring out why, and now I'm no longer a Sprint customer I'm not very interested now either.
