Im testing daily with my AH Account and the ping literally spikes at between 19:00 and 19:30 like clockwork and vanishes late at night, like 11:00 or 12:00 and I distinctly remember this happening a few months back and a lot of people complained. It seems to be repeating itself again and seems to be a problem for a lot of people.
I constantly sit with "Poor connection to host server" in The Division but the moment I switch to my VOX backup account it goes away and pings are rock solid. Switch back to Afrihost and ping a number of servers directly and the moment it reaches the international breakout the ping is horrid again. Diablo jumps from 180 to 300+, WoW jumps to 300+, Smyte jumps to 400+ etc. etc. Switch back to VOX and its like microwaved butter, runny and smooth. There is definitely something up and the NOC team need to find it fast.
The guys are running end to end tests, and we're working with as many users as we can to find the issue. I totally understand your frustration here, I promise you were are not ignoring this issue.
