While walking my dog I witnessed a constant "herd" of hundreds of satellites travel across the sky for 33 minutes.

While walking my dog on Tuesday from 9:45-10:18 ((p.m.)), I witnessed a constant flow of hundreds of satellites travel across the sky for roughly 33 minutes.
The satellites were traveling from a north east to south west direction.  It looked as if someone cast a net of hundreds of satellites over the sky.  They traveled in the same direction were similar sizes and moved at the same constant speed.  The sky was so full of these satellites that it reminded me of watching rush hour traffic on the freeway.  I watched until the “satellite traffic” thinned out and cloud cover obstructed my view.
I want to make it clear that I saw HUNDREDS of satellites and these were not the Star Link constellation or any type of meteor shower.  I am an avid sky watcher and know that these were satellites.  I realize that you collect UFO sightings, but I didn't know where else to share what I witnessed.  I’m curious to know if anyone else reported seeing them or if anyone knows what their purpose might be.
