I've recently been on a hunt - I'm currently on a contract in the Bay
Area, but I am still doing some sysadmin for an ISP back in montana.
The Montana ISP is Sprint connected. For my local connection in Hayward,
CA, I signed up with PACbell, figuring that it would do until I found
another provider. After two months I had had enough and went on a quest
for another provider.
What I discovered is that If I did an extended ping to any provider in my
local calling area, I had at least 5% packet loss (the provider I am
using right now was at 5%). Pacbell was around 50%. Others varied. By
contrast, I can ping any sprint-customer-attached computer and have
almost 0% packet loss (1 out of 1000 lost occassionaly). Unfortunately I
couldn't find a local provider which was spirnt connected. (An aside:
anyone who knows a local priver in hayward which is sprint-connected is
more than welcome to contact me directly :)
>From traceroutes and additional extended pings, I could tell that some of
the loss was at exchange points - other times the loss was in internal
networks.
IS there a reason that I'm getting 5 - 50% loss outside of sprint? I've
also played a bit with this from a couple of other providers with similar
results.
As much as I hate to say anything nice about sprint, I'd have to say that
they're very good about not loosing packets, at least when they're BGP
hasn't imploded.
