Latest on Mae-WEST outage

Just called MFS and they said that they have restored power but the Gigaswitches have lost their configuration and the technicians are working to restore configs now. I would suggest that we expect a lengthy outage. > So did Mae-West fall into the ocean out there or what? Does anybody know? > Todd R. Stroup > Fiber Network Solutions, Inc.

We are still up... for the time being at least.... heh.... I guess the guy wielding the chainsaw missed our power cables! Or was it a Ryder Truck? But 75% of our peers are down...

One of the benefits of being in the building is that if they don't answer their phone... we can kick down the door. Our guys are down there now. According to our guys, it is a power problem... but they are getting details... I will post as soon as I know....

Re: Network Monitoring Tools
by William B. Norton 11 Jul '97

Hi David - Your question is well-timed. I just put up for anonymous FTP the Rover 4.0 code (beta). The previous versions of Internet Rover code has been in use since the NSFNET days and has been downloaded and put in production in many locations around the world. The original idea was to code a simple way to perform tests on network devices and create alerts when the tests failed. Many folks have added tests to the package and contributed them back for incorporation into the software. Current tests include: WWW, Named, SMTP, FTP, TELNET, PING, PORT, etc. Basically, if you can make a subroutine that returns a Pass/Fail, it can be incorporated into the code. These earlier versions of the code has scaled to about a thousand nodes in our NOC. This 4.0 version uses SNMP to externalize the list of alerts that Rover generates to centralized network management station(s) for consolidation into a single aggregate alert screen. This allows one to distribute the monitoring function as appropriate and only pull back the list of what is broken in the area. The cool thing is you can then build your hierarchy of management stations in a lego block approach. Currently the code has only been ported/tested on Solaris and SunOS systems. The real release is going out after some other folks verify that it works in their environment -- let me know your experiences with it... It shouldn't take long to install: edit a couple files and type ./configure;make The beta code and documentation is at: http://www.merit.edu/internet.tools/rover Hope this helps.

It's always fun
by Robert Bowman 11 Jul '97

It's always fun when the major West coast IXP goes down--Mae-West MFS. Every peer from our Mae-West NASA AMES router to MFS is down, as well as our MFS router. I'd suppose everyone else is seeing the same thing. And the MFS NOC isn't answering the phone, after being on hold for 15 mins. Anyone know what is going on? Rob Exodus

Ticket 94946 is open at MFS. There is 80% down at Mae-West MFS side, according to the woman on the phone. Nobody is down at NASA-AMES, best I can see on our router.. but AMES is isolated from MFS, and our MFS router cannot hit anyone that I know of at Mae-West MFS. A fun Friday in the making.

This means that *IF* your new connection is being measured as 4Mbps of cell bandwisth, you will only be getting 3.18Mbps. You may want to verify from the company providing this link what exactly are they limiting you to? btw, the extra overhead is lost in things like the last cell of a packet not being full, etc. Chris A.

It went from advertising it with an MED of 0 to an MED of 20 and back, to just readvertising it over and over with the fixed default MED I'd set (1). The sad thing is that until flap damping code was added, this sort of bug was masked... but now I have a few dozen customers totally offline. -matthew
