[Dxspider-support] IK5ZUK-6 node shutdown

[IK5ZUK Luigi]

Hello,

The DXSpider node IK5ZUK-6 at ik5zuk.dyndns.org:7300 is gone permanently 
offline after 15 years of service.
Thanks to Dirk, G1TLH, for providing an excellent dx-cluster software 
and support all over the years.

All the link partners are invited to remove any reference to it from 
your node's configurations.

Thank you and best wishes to all.

73,
Luigi IK5ZUK
