when I try to access their website: www.autotrader.co.uk - I get Accesss Denied error, been happeing since onday this week.

hmmmm, anyone else get this? time to clear cookies? other?

It was having a denial of service attack which started on Monday, and it's been a bit flaky since. Seems fine for me this morning, try clearing your temp internet files, you might just have cached the error pages...

Just tried, no luck for me either.

Spent an hour on it this morning. Working fine.

we are the security company looking into the attacks.

millions of unique users over normal.

Its a bot.
