How would one go about filtering AS2906 on one feed? I can control my outbound
traffic but I don't have a lot of control over who sends what in.

Seems like there are many moving parts to this. Upstream routes, downstream
routes, DNS, and whatever anycast tricks Netflix does.
I would imagine both Level3 and Cogent have on net Netflix servers, and that
the worst situation would be the traffic has to go from one of them to the
other in order to reach you.
Might need to contact Netflix and get their engineers to help you troubleshoot.

One thing to keep in mind is where your resolving DNS servers sit. Keep them
on-net for the best performance.

Netflix may also be caching your IP range for CDN selection. You change from
one upstream to another, and they're still distributing from the old place?

With that connection up, filter Netflix's AS from your Level 3 feed and see if
it still works properly with both connections up, but Netflix only available
over Cogent?

L3 is hosting most of the Netflix content. They prefer to send it to me over
the L3 connection. Someone with a VM connected to L3 in another DC in Baltimore
just reached out to me and they are not seeing the same issue so it might be
connection specific.

I just brought up a Gig level3 connection and now fast.com shows speed tests in
the ~5m range while speedtest.net shows correct speeds, i.e 200m on a 200m
plan. If I drop BGP to Level3, fast.com speeds increase to 100m+
Two feeds in the same data center. Each connected to a juniper MX5 with fiber
between the MX5s.
If I drop BGP on the cogent feed, fast.com tests are still around 5m with good
speeds to everything else.
What seems to be nuts abut this is that Level3 appears to be hosting or
directly connected to the netflix content servers that feed data for fast.com
as far as I can tell.
The spike in netflix traffic coming in over the cogent feed is when I dropped
bgp on the lvl3 feed to run fast.com speed tests.
Has anyone else seen this with level3? Could someone else with a level 3
connection test to fast.com and let me know what it looks like?
