Fastly CDN causing SLOW Reddit image load

I’ve noticed for the past week or so my images/media from i-redd-it load super slowly. Here is a video of the occurrence happening on AT&T 300Mbps fiber.

Continuing post of tracert and fastly-debug below. (where’d it go?).

Here is my tracert output:

C:\Users\abc>tracert i.redd.it

Thank you. Any help would be appreciated.

It looks like our system spam filters flagged the reply with the debug info. I restored it and I’ll pass this in to our network engineering team.

Are you in Texas, per chance?

We’re noticing slowdown from our colo in Austin, but not from other sites. It’s intermittent, but fairly easy to reproduce by doing repeated downloads of a large file:
