Nice to be back on air, what caused this? Don't think it was a server fault. The web as a whole has been a little slow tonight. j. :o(

It has been awful tonight. I was beginning to think my son had played about with my settings. (he said not). I can always blame him! Anyway hopefully back to normal surfing.

Web still crawling along here in the Scottish Borders. Cps in count is up and down like a Yo-Yo.

click here Link from VoG may explain the reason? "Denial of service attack" not quite sure what this is but I'm sure someone will explain for us. j.

Well just been on another thread and they were saying zone alarm has caused the prob tonight so disabled it and all perfect now.

As long as I can surf again im not bothered. They better not make a habit of it. When you cant get your emails or surf its bad. My comp is my life line.

This is an attempt to flood servers with to much information to make it crash and to block legitimate users out.
How it effects everyone else I'm not sure.... Can any one explain?

I assume that large parts of the network had been flooded with packets of information both from people trying to bring ZoneLabs down (sites still not available) but also from people trying to visit the ZoneLabs websites. If an ISP's DNS was trying to locate ZoneLabs websites it would've had problems doing so increasing the time it took to do anything else.

Not a very good advert for a security company!

  Jester2K II 08:08 26 Nov 2003

So Blueyonder (my ISP) would have had it servers looking for the ZoneLabs website and hence my requests for PCA site, Dilbert etc etc would be waiting at the back of the queue (as it were) whilst BY is trying to find ZLabs!!

I see!!


However I'm curious about this comment - Not a very good advert for a security company!

Could ZL have done something to prevent the DDoS attack? Or is there something they could / should have done when it started?

Some links that may help explain things??

The people who started this attack off have no doubt found a flaw in a system to be able to do it. It used to be true that you could do a 'ping of death' against a system and that would slow it up/bring it down. Systems can now be protected against such things.
