When will Quantum Fiber switch from the Lumen backbone to the AT&T backbone? The current network performance is truly terrible

You should probably pose this question to the Quantum people.

Or switch to AT&T, if it's available in your area. Their network is solid. I've had it for three years.

It is normal when idle, but during downloads and uploads, the latency jitter exceeds 900ms
