Is Verizon having issues in the 80601 zip code?

I recently signed up for Verizon service and am using a Droid Turbo.  At my home and around town I'm only getting one or two bars of 4G service, and the phone has dropped to 3G on several occasions, still with only one or two bars of coverage.  Data throughput tests using apps such as Speedtest and OpenSignal show very poor results, with speeds well below 1Mbps.  I switched from another carrier in hopes of improving my coverage but I'm starting to get concerned.

Thanks in advance for any assistance.
