I'm using youtube only occasionally and last use was some days ago, so |
28 |
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 |
31 |
addresses. Maybe the DNS implementation on your DSL modem only cache |
32 |
the first one. If this IP then is not reachable for some reason, it |
33 |
would lead to an "Unknow Host Error" till the TTL of the cached entry is |
34 |
reached and the modem is doing the next lookup. |
35 |
|
36 |
But that's just a thought. Maybe your modem really was hacked. |
