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? -Deepak.

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).

Has everyone else been seeing the almost daily UUnet outages recently, does anyone know what the true causes of these have been?
