> I’m just getting the default route from both upstream routers.

If they offer the option, instead of a "default-only" feed from each ISP, you may wish to see if they have "default-plus-our-customers" feed: if Service A is also a customer of ISP #1, then why bother sending the packets to ISP #2 in the first place?

In general, at some point you'll hit a Tier 1 network, after which it won't matter, but until that point getting the connectivity to other customers of the ISPs could be useful. The other reachability destination to pay attention to would be of IXPs, where CDNs often connect to.

Both of the upstream routers are mine, there’s no difference to the routes they have available. (They’re connected both to Tier 1 transit as well as the major local IXP)
