Smurf tone down
by alex＠nac.net 01 May '99

01 May '99

Hello, To help quench the effects of smurf attacks on our network, we CEF-CAR all ICMP on our egress points to about 200% of normal ICMP flows. However, when a upstream becomes full of ICMP (even though we dump most of it), it still affects our external connectivity. My question is, why don't larger upstream providers use CEF-CAR (assuming that most use this) do the same to limit the effect of smurf attacks on thier (and subsequently, thier customers') networks? The floor is open for flames. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Atheism is a non-prophet organization. I route, therefore I am.

Geez, did someone let some of Milosevic's people in the country with backhoes? I've now also received a report of a Texas fiber cut (frontier or als) and outages in Deleware, Ohio, Maryland, Michigan, New York, Pennsylvania, Virginia, West Virginia (mci or worldcom). It still isn't clear if there is one or more than one cut in the northeast. I'm also not sure where the Tennessee and Florida outages are originating, or if they are connected with the ones mentioned above. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

The guy I just got off the phone with told me that this particular cut will likely be down all night. I'd post this to NANOG, but I didn't sign up for posting access, since I don't really have much to post. :-) If you could post it, I'd greatly appreciate it. :-) Cheers.. -Pat "One World, One Web, One Program." - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Führer" - Adolf Hitler << End forwarded message

Thanks for the Hawaii update. As one person said, the backhoes are trying to make the end-of-month quota. Just to spread this out over a few more carriers. A person reported an OC-48 outage hit Los Angeles early this morning (gte?), so it looks like both coasts are getting hit. Today's animal incident report. A deer got tangled in some power cables at a microwave relay station outside of Colorado Springs(us west) on April 27 disrupting emergency phone service for eight hours. Why does the animal kingdom hate US West? Last year's gopher took out a US West facility too. Today's money request.

Thanks for the correction. I have never heard of these cities so I tried. Both of these outages were reported by WCOM. There are two major routes from Philly to DC. One of these routes are between Pittsburgh and DC and the alt route is between NY and DC. Remember, these are reports from WCOM. CJ Vince Fuller wrote: > > I have a report from my NOC.

Major WCOM Fiber cut in Ohio
by Brandon Applegate 30 Apr '99

30 Apr '99

Our CLEC (Time Warner Telecom) tells me that there is some type of major fiber cut on the WCOM network in Ohio. This is affecting our ability to dial LD (without a PIC code) as well as inbound on our 888 number (which is actually switched by Qwest) and several other long haul circuits. Anyone have any more info or corrections on this ?? -------------------------------------------------- Brandon Applegate, CCNA : Network Administrator http://www.one.net : brandon(a)one.net --------------------------------------------------

OUTAGE: multiple outages around the country
by Sean Donelan 30 Apr '99

30 Apr '99

There seems to be multiple outages (some providers have said fiber cuts) around the country. Places I know about are Eastern Tennessee Northern New Jersey Central Florida I don't know if there is a common cause, or if Murphy just thought it was a nice spring day. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
