Poor Connection to Seattle

[#1]

On the Internet 150 plan. Not the account owner, but a tenant. Recently accessing some websites (namely Reddit) became incredibly slow. I tested a bit on 2 devices (Windows laptop and iPhone) and I think the issue is with Shaw's connection to Seattle, or some CDNs in Seattle. Take a look at the following test results:

Reference: UBC

Seattle connections:

I also tested other cities:

Steps Taken:

Restarted modem

Rebooted devices

Any help troubleshooting?

Edit: A test to PNAP-SEA, by Internap Network yields 0.4MBPS! This one is from netperf.tools, all other networks in Seattle there yields good connection:

Curious..  If you re-run the tests today, are the results any better?

Ping times are a bit high, but speed is not bad.
