We are working on a new site which is hosted on Rackspace. http://travelcafe.co

For some inexplicable reason we have intermittent connection problems when trying to access this site and the wordpress backend. We're able to access it for an hour or two and then it becomes unavailable and this can be for an hour or more. During those time we get an "Error 101"

Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.

This problem is almost certainly unique to our location / ADSL connection. We've had people at other locations check at the same time as we cannot access the site, and at that same time they can. We've also checked out the site using the 3G network and it's accessible when we're having problems from our ADSL connection.

We have tried using fixed DNS addresses (Telecom's, then Google's and then Open DNS)
We have binned the Dynalink RTA1025W ADSL Modem thinking it was an issue with the modem.
We tried the standard Thomson Telecom Modem but that caused even more problems (binned that one too.)
We have now installed a new Linksys WAG160N but we have the same issue (but a prettier modem)

Discussions with Telecom Support have been fruitless

We connect (in case it's not already obvious) via Telecom ADSL network. I'm based in Manly, Auckland. Our connection is otherwise fine although we have noticed on some of our devices recently that Facebook and Google.co.nz are unavailable for a short time. Often coming right within 30 seconds or so. This may be related.

The domain name Travelcafe.co is registered with GoDaddy. I'm about to move it to Rackspace as well and see if that helps. (Rackspace think not, but I'll do it anyway to keep things clean.)

If you've encountered similar issues with intermittent errors on specific sites I would be extremely grateful for any advice / assistance.

Thanks
