Yes, we're seeing first-hop failures on our connection in Equinix.
We were still getting a full table from our Equinix Direct peer
before we shut it off. I'm uncertain if it's a L3 or an ED problem -
are you on ED or L3 direct?

Got any traceroutes to help clarify "weird routing"? :-)

Maybe you're talking about something completely different (if so please
state such, as no one needs improper correlation of two separate
issues), but for the past 2, possibly 3 weeks I've seen sporadic
problems (increased packet loss, but no latency) specific to the San
Jose area of L3's network.

I checked on this issue a few minutes ago, and it looks like the most
recent example I have of it is from 15:26 PDT today, and lasted about 4
minutes. I have to remove the preceeding hops for security purposes,
sorry. Loss starts here:

8. 4.68.18.126 6.7% 60 14.7 21.0 3.6 45.4 11.5
9. 4.69.134.213 5.0% 60 12.9 30.2 3.6 58.2 19.1
10. 4.69.132.14 5.0% 60 53.0 43.9 14.8 70.1 14.4
11. 4.69.132.78 6.7% 60 57.5 51.0 44.2 92.6 7.8
12. 4.69.135.1 5.0% 60 46.8 61.9 44.2 233.6 41.1
