Re: Plethora of UUnet outages and instabilities

My first question is: Have you ever tried putting an RSP2 in a 7505? It 
ships with an RSP, second, have you tried putting an RSP4 in a 7505? It 
works too. Cisco isn't real happy about it, and of course I wouldn't 
recommend it, but it works.

Next, if your network is that busy, you honestly don't keep that 
kind of spare/upgrade equipment around?

Thats my point. It often ISN'T easy. For example, say you've got a
7505 in one spot and find its getting killed. You can't put an rsp4 in
a 7505. You've got to replace the router. Anyone got any spare 7507s
or 7513s lying around? Chances are that if they do, its 2 or 3.

Its actually going to be a bit more problematic to split the load
between two routers since that can mean notable changes in the
internal routing or the BGP tables. Not to mention calculating what
kind of traffic is going to pass BETWEEN the two routers.

Straightforward, yes. Easy, no.

Why wouldn't upgrading the router's CPU or splitting the load between two 
separate routers solve the problem? Maybe that's not an overnight 
solution [unless you have spare RSPs in the POP/colo point] but it seems 
pretty straight forward to me.

I know one of the problems that UUNET has been having (and I believe
several other folks as well) is high CPU usage on many of their
routers. (When the ping times to the router itself get high its either
a congested link or, usually, a router thats spinning hard..) However,
thats not a problem you can fix easily or fix overnight.

Oh God, NYC1.  Look out for that ugly beast...  We are unfortunate enough
to have a connection off of that thing.  The NOC is good, if you're up for
entertainment.  Let me count the times I've heard "what's traceroute" on
the phone with them.  Let me tell you about outages where they "forgot to
take the loopback off the T" for like 6 hours.  Or my favorite (once you
hit a high-level brainwashed engineer) the good old "I don't see *any*
packet loss, so everything is OK".  "Yes, but I'm seeing ping times of
500ms to your router, and our line isn't near saturation by a long
shot"...  "I don't see any packet loss", etc...

blech.  I would not recommend them to my worst enemy.

All I know is they suck moose nipples, and I disconnected from them last
week. They have been having problems in/around cr1.nyc1 for MONTHS now, and
they are doing nothing (that I can see) to fix it. Thier first-level
support is horrendous. One guy once said to me, "Routers have
processors?!". Another hung up when I told him to put "CUSTOMER IS IRATE"
on the trouble ticket. 

There are some GOOD guys over there, but them seem to be disappearing? (are
you there, Mr. Hannan?)

HELLO, GENUITY (anyone who is looking for a new provider, Genuity is DAMN
good. and a DAMN good NOC. Sales guys are a little whacky, tho).

does anyone know what the true causes of these have been?
