Grosse Pointes/Harper Woods feed offline?

[Nine29]

How do I contact the provider of feed that's down if they don't have the link to "Report a Problem"? The Grosse Pointes/Harper Woods feed has been down for awhile now. Feed can be found at:

Harper Woods/Grosse Pointes Fire, EMS, and Police Live Scanner Audio Feed

I'm willing to provide this feed if the current provider is no longer able.
