High latency at night

I just switch to fiber two days ago and I have major ping spikes in the evening (90 - 130 ms). So far I’ve only tried the standard speed test sites during the problem, but ran tracert to both Google and cloud flare when the issue was not present this morning. I got around 2 on the first few hops and 10 on hop for and five.

Has anyone had any success in resolving a similar issue?

Minneapolis area, Q1000K, transparent bridge mode, VLAN tagging on ONT, 8888 and 8844 DNS.

The only change I have made this morning while everything is working as expected (~1100 up/down 2 ms) is switching to the 1g port. I do plan on periodically taking screenshots of each hop through the day to track. I also plan on trying 1111/1001 during periods of high latency to see if that helps.

Any help is appreciated.

Edit: Sunday night

At about 7pm, it's back

using Quantum, Google, and CloudFlare DNS, hop 2 to 7 are all above 100 ms while hop 1 is <1 ms. Safe to say it's either at the pole or local hub. I'll try the exec and success emails first as the weekend L1 call center is not the best...

Edit 2: Tuesday morning

The lumen exec address got back to me early the next day. Said it’s not their problem as AT&T owns Minnesota (word, fair) but they did forward my email to quantum’s escalation team and gave me a case number.

Edit 3: Tuesday morning

I received a call from the office of the president of AT&T. They are looking into my issue and committed to an update by tomorrow.

Super nice on the phone, already feel way better about switching from Comcast. I am a little embarrassed it escalated so high for one customers issue but it’s a good feeling when you know they are really looking into it.
