I see either a routing loop or a wonderful !h (no route to host) on at least a daily basis when going through sprint. I find it particularly amazing that this never happens once I get into the MCI network or ANS or etc etc (Well, ok it happens every few months from what I can see). Right now the most frequent complaint about our service is Sprint f*cking up. I am looking forward to Jan 2 when I switch companies and I won't have to deal with Sprint anymore. (We're going right into MAE-East so any screw ups will either be mine or will only effect traffic to the one provider thats down and not everyone). Sprint and Net-99 should get together sometime so that they can build a slow, unstable backbone, they each seem to have mastered only one of the two. On Tue, 19 Dec 1995 dlewis@Teir.COM wrote:

Its days like this when I just love sprint:

Sadly this is all too common of an occurrence. What is sprint doing to help keep problems like this from becoming chronic? Is it just me or is Sprint particularly bad about this?

I guess the reason that I'm bringing this up here is I wonder if these types of problems are the result of any particular choices Sprint made in their design.... If so I would like to know how to avoid them. :)

I know that hardware fails and things break, but Sprint has had (in my opinion) more than it's share of problems.
