The 24h period is fixed but unfortunately such a script would be very
fragile. E.g. it could happen that the connection is lost during failure
on the providers side. There I hoped wget could be forced into retrying to
resolve hostnames more than only one time. If thats not possible I'll try
to hack something in the wget source together as this looks more reliable
to me than a script which tries to control wget externally.
