(Our network engineers have now isolated the cause of the problem which is believed to be due to a targeted denial of service attack on one of our customers. We are in the process of getting in contact with this user and will continue to monitor the situation overnight)
a dos attack on one customer can cause a edge router to be over used and bring browsing web to crawl/stop all all togther for all users?

Cisco, Juniper (whose routers PN use to terminate the pipes) and other try and build in a fair amount of mitigation into their software and hardware platforms but like any software, it will fail if overloaded with requests.

Were the issues lingering into the evening as I was bumped off about 6 and it took a while to recover or was it just likely to be my dodgy line.

eat some humble pie they said to me.
i could do a dns look up from the router config page. so just disconnected from PN and back again to jump gateways which worked.
was going to post on the forum about it but checked the service status just b4 i did and found you where all ready on top of it.
no call from pn to me so wasnt me that was getting dos attacked thank god.
was this a big dos attack to effect the edge router or just like you say the software had a paddy about this average sized dos attack?
