Pretty much the only regions on the planet from which we *don't* see regular volumetric DDOS against www.bbc.co.uk & www.bbc.com is central Africa & the poles.
This is map shows the number of time each country was a DDOS traffic source in the last 30 days (larger circles == more DDOS attacks).
The botnets are really well globally distributed these days (and we typically see thousands or tens of thousands of source IPs per attack - mostly compromised servers).
