"The internet is slow"

Mailman List Mirror (Read Only)

Gah.. I hate these kind of vague problems.

I have multiple users complaining about "the internet is slow"; specifically
to sites such as aol, cnn, amazon. Our support folks are also having trouble
getting to postini's admin pages. Things are excruciatingly slow.

I don't see any indications on router load, link utilization, bouncing routes,
etc. that jump up as obvious problems.

I tried using the lookingglass at algx.net, but I'm getting null responses for
all requests (ping, traceroute and BGP). I'm not, however, seeing any issues
with traceroute servers getting to us.

Anybody know of anything broken anywhere? I don't think the problem is us, but
if somebody would like to respond off-list with any oddities you may see with
AS6423, and/or traceroutes to 206.103.37.166, I'd appreciate it.

Thanks,
Rick

I got quite a few responses in a very short period of time.

a) DNS resolve problems - already checked, looks OK
b) traceroutes - Multiple reports of packet loss through UUNET,
                          but some look fine. Ticket opened with UUNET.
c) overloaded routers - CPU load looks fine. One report of high latency
                          on one of our cour routers appears to be an
                          anomaly.

FWIW, mtr output was the most useful for me in this case.

Thanks for the responses.

Packet loss within UUNET, apparently localized to the Portland (OR) area.
I've turned down our peer with them and things are looking much better.

Thanks for all the help/responses.

Shhhhhhh, next thing you know some reporter is going to be writing a
story about how the NANOG mailing list fixed that darn "the internet is
slow" problem everyone has been complaining about.
