[clug] ISP questions again

[Stephen Walsh]

Thanks Stephen and Brian;

I suppose I should have specified that I have been monitoring the server
whilst these spikes are happening, and as far as I can see the server is not
handling any requests for either HTTP or SMTP.

It might just be Transact playing up (colour me surprised), but repeated
requests to them have confirmed that I definitely have a 1Mb link
provisioned and there is no problems with the IRX.

I'll keep looking upstream, I suppose the big test will be when we get the
ADSL connected, I might move the server and see if the pings stabilise.

Steve
