Recently I had a problem with Paradise where traceroutes only went as far as
ipnet2.paradise.net.nz and I couldn't reach DNS servers, Paradise's web site
or anything useful basically. This lasted at least 10 minutes, but I didn't
have to reboot, I just had to wait it out..

I've also had problems with Paradise where I find it very hard to connect,
but generally the service seems to work when I'm connected. And recently I
haven't had a drop out. <crosses fingers>

I've noticed that when Paradise isn't working the jetstream games realm
seems to work okay. But I don't like to change realms, as I'm paranoid that
I may not be able to connect again.

The problem as I see it is that there's very little in the way of choice for
reliable DSL providers. I'd considered using ihug, and mailed
sales@ihug.co.nz but got no reply, so I think that basically means that I
can't consider them..

When I used to use Paradise cable I had much more infrequent problems, and
when there was a problem it was usually a partial problem, such as very
annoyingly high levels of packet loss. (over 60%)

There was also another outage at some time that I didn't notice - I've been
graphing ping and packet loss using mrtg. Packet loss is very common, and
often high but I understand that that's because of Telecom using policing
rather than shaping and only having a 128kbit limit. (which is near
impossible to contain within by doing anything about for received traffic)

I really wish there was some nice way that I could control acking of
packets or such, to avoid the packet loss, but I've been unable to think of
any way of doing that without making changes to the TCP/IP stack which I'd
rather not do myself.

Ben.
