Sprint routing issues
by jlewis＠lewis.org 23 Mar '00

23 Mar '00

Is it just me or is Sprint having issues tonight? I noticed some routing problems getting to C&W hosted sites via Sprint. When I tried to go to www.sprint.net, I couldn't resolve it. According to F, sprint.net's NS's are: NS1-AUTH.SPRINTLINK.net. 2D IN A 206.228.179.10 NS2-AUTH.SPRINTLINK.net. 2D IN A 144.228.254.10 NS3-AUTH.SPRINTLINK.net. 2D IN A 144.228.255.10 These are all currently unreachable from our site (directly connected to Sprint and UUNet) and multiple offsite locations on other backbones. If I traceroute from atlantic.net (goes out via Sprint) to my own site (www.lewis.org) hosted off a C&W T1, I get 2 hops into C&W, and then nothing. If I trace from www.lewis.org to atlantic.net, I get 2 hops into Sprint, and then nothing. Before anyone asks...yes, I did call Sprint and run this all by them...and they opened a ticket...but the fact that seemed more interested in doing intrusive testing on our T3 than looking at their own network didn't instill much confidence. ---------------------------------------------------------------------- Jon Lewis *jlewis(a)lewis.org*| Spammers will be winnuked or System Administrator | nestea'd...whatever it takes Atlantic Net | to get the job done. _________http://www.lewis.org/~jlewis/pgp for PGP public key__________

Lucent AccessPoint 450
by Oleg Shpak 21 Mar '00

21 Mar '00

Does anybody have an experience with Lucent AccessPoint 450 ? How reliable this equipment ? Are you pleased to use it ? I have looked for Cisco7204, but AccessPoint looks fine too, especially its price. I need to connect company office to two poviders via bursted T3 links. I need to do load balancing between these links in both direction. It must do bgp, possible ospf, access-lists, maybe traffic shaping. Thanks, Oleg Shpak.

non-op
by James Paul 20 Mar '00

20 Mar '00

I apologize if this is off topoic I am researching the deployment of a free personal web-hosting service. Normally each user's html documents reside in a subdirectory of the document tree where the subdirectory is named for the user. /htdocs/ / \ / \ user1 userN Thus a users URL is www.site.com/userN. We currently have about 5000 users on the service. This is spread across three different single directory filesystems. As the number of users grows I imagine that this will become unworkable due to the nature of the file systems. One solution is to put groups of users in several subdirectories but this could make the user URLs messy. www.site.com/sub1/sub2/userN Can someone please comment on methods of keeping short clean user URLs while making the storage of many small web-pages more efficient and scaleable? What kind of backends are currently being used to serve up plain old static content with inline stuff? Also, how are directories being indexed for retrieval? How have are the larger installations currently working this? Thanks in advance, James Paul

FCC's NRIC to monitor ISP outages
by Robert Cannon 20 Mar '00

20 Mar '00

NRIC V had its first meeting today. NRIC is a Federal Advisory Counsil providing information to the FCC on telecommunications (ie telephone) network reliability. Information on NRIC can be found at www.nric.org The Chair of NRIC is Jim Crowe from Level3. The primary focus of this NRIC will be to continue the network reliability work of the group, including packet switched networks. NRIC will be broken into the following subgroups (1) Y2K - finishing the work (2) Network Reliability and (3) Interoperability. NRIC IV recommended that a one year voluntary trial period of network outage reporting be initiated for a wide variety of communications service providers, including Internet Service Providers. The final report of NRIC IV's recommendations in this area can be found at http://www.atis.org/atis/nricgr3.htm The relevant language from the Executive Summary is below. This Report was placed on the web for public comment in February for public comment. Those comments were received and incorporated. The recommendation has been accepted by NRIC. Thus, presumably, NRIC will move forward to initiate a one year voluntary trial period of ISPs report outages to NCC/NCS, NRIC, and ultimately to the FCC. At the completion of the trial, an analysis will be done of the usefulness of the reporting. NRIC indicates that the issue of ISP involvement in the voluntary reporting was supported by Ira Richter of IOPS www.iops.org The presentations from todays NRIC meeting should soon be on the NRIC website www.nric.org Exec Summary: "A voluntary trial is recommended with participation by service providers of CMRS, satellite, cable, data networking and INTERNET SERVICE PROVIDERS (ISPs) to alert National Communications Systems/National Coordinating Center for Telecommunications (NCS/NCC) of outages that are likely to have a significant public impact. "* Industry associations should provide an informational notice to their membership to inform them of a voluntary outage reporting trial and encourage their participation. "* Analysis of the data from this voluntary trial should be done by a neutral party. This analysis should be similar to scope to the analysis conducted on wireline carrier segments. "* At the completion of a voluntary trial period (minimum 1-year) an evaluation of the effectiveness of the data for usefulness to participants and the FCC should be understaken. "Industry communication of NRIC IV 'Best Practices' to CMRS, Satellite, cable, ISP, data networking service providers is recommended." -B www.cybertelecom.org cannon(a)world.oberlin.edu Views Dey Are My Own ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup
