We have a number of clients in the Wellington area that have been
experiencing short duration connectivity issues. We see it as a short
duration of packet loss. The DSL does not transition up or down.

It only appears to affect Xtra customers.

What area are you in?

Subject: OT: Non-ADSL(?) connection problems...

Hi Folks,

I am posting here in desperation, as I am not sure where else to turn.

I am getting nowhere fast with xtra's service desk team.

I have a really strange problem:

Up to 15 times a day I am unable to access anything beyond the first hop
in
xtra's network.

It effects multiple PC's.

I first noticed this when my vpn connections started dropping out and my
ssh
sessions started dying. It started about 2 months ago, I have been on
this
site using this equipment for about 12 months before the problems
started.

My network configuration is thus (via a traceroute to smtp.xtra.co.nz):

PC(s) -> ADSL Router (192.168.1.1) -> 222.155.0.1 -> 222.153.221.79 ->
.......

Now what happens is up to 15 times a day (the worst, usually its 2 or 3
times a day) for 30-60 seconds I am unable to ping 222.153.221.79.

I AM able to ping 222.155.0.1, but I cant get to anything beyond it.

The ADSL line is not dropping (according to Xtra and my modem, and if it
was
dropping I wouldn't be able to ping 222.155.0.1).

I have set up three scripts on the main PC (it happens to all the PC's).
The first two scripts ping 222.155.0.1. and 222.153.221.79 every 10
seconds
and log any outages (And email me when the connection returns).
The third script does a traceroute to smtp.xtra.co.nz every 30 seconds
and
logs the output.

I have the extact dates, timesand durations of the outages. I have ping
logs. I have traceroute logs.

Xtra are saying they can not (will not) do anything. They are saying as
far
as they are concerned there are no outages taking place. But they are
only
looking at the PPP/ADSL side of things between the exchange and my adsl
modem, so they would not see anything.

Does anyone have any ideas on anything I can try?

I am completely out of ideas.

Kind Regards,
