Since feeds are provided by volunteers, who use their own equipment for the feeds, it is possible they had equipment issues and couldn't afford to replace it, or got tired of running the feeds. It is unfortunate, but happens. I was in this situation for a local feed I ran for several years and finally had to give it up.
There was until recently an online scanner that had a channel to monitor all 5 nyc boroughs replicating a true scanner. About a week ago it stopped connecting. Anyone seeing this too? Anybody know why?
