I'm using youtube only occasionally and last use was some days ago, so I don't know if there was something unusual today. When I do a nslookup www.youtube.com, I get a whole bunch of IP addresses. Maybe the DNS implementation on your DSL modem only cache the first one. If this IP then is not reachable for some reason, it would lead to an "Unknow Host Error" till the TTL of the cached entry is reached and the modem is doing the next lookup. But that's just a thought. Maybe your modem really was hacked. -- Regards wabe
