Pessimistic estimates say that the problem we suspect (a DNS proxy that cannot handle AAAA queries) affects about 0.5% of the global userbase. 50% of those can easily be fixed with a firmware upgrade of their router, which is usually a very good idea anyway.
I'm sure there are regions with higher rates if a large provider gave out broken systems, but generally saying that all Ubuntu 9.10 installations are affected and everyone has to purchase new routers is pure FUD. For the record, this bug can easily be tested with the following tools $ time dig -t a noc.sixxs.net +nofail | grep -e status -e A -e time ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 26324 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 3, ADDITIONAL: 0 ;noc.sixxs.net.
