Once a domain name is resolved, its record can be cached by the OS (or even
by the app itself). Thus, the application(skype in this case) can keep
working even if the DNS server is not reachable after that.
Using netstat, check what connections skype has made and try to ping those
sites by name and IP address. Both should work IMO.
