I've had reports from at least 10 people from New York to Virginia on 1 Gbps Verizon FiOS stating they're experiencing complete intermittent drops in connectivity to apps such as Zoom, GoToMeeting, and even DNS resolution via 1.1.1.1 and 8.8.8.8.
After doing a fair amount of digging, I can correlate times where there are total connectivity drops from the Verizon FiOS network to these external destinations.
--- 1.1.1.1 ping statistics ---
10000 packets transmitted, 9954 packets received, 0.5% packet loss
round-trip min/avg/max/stddev = 4.769/9.777/114.903/7.403 ms
--- 8.8.8.8 ping statistics ---
10000 packets transmitted, 9965 packets received, 0.3% packet loss
round-trip min/avg/max/stddev = 4.041/9.355/114.905/7.335 ms
Within the Zoom application itself, observing 82ms of latency, 3ms jitter and ongoing 24.0-28.8% packet loss.
There are times where 4-5 users will be on a call at the same time, and all of the FiOS users specifically drop. The users are spread across the East Coast, so it's not isolated to a specific area.
This has become more serious over the last few days, with the return of students to school (which isn't a factor in my household, but I'm experiencing the same issues).
This all appears to me like there are saturation issues occurring within Verizon's network to external providers.
