...but the OP stated that he doesn't do any BGP with either upstream,
and instead relies on the upstreams to statically route the block to

I'm mis-understanding something.

The OP has two 'transit' providers, neither of which he has a BGP
session established. Both of his upstream ISPs provide transit for him
to the wider Internet.

Traverses. ie. my upstream providers provide 'transit' services for
networks that I advertise to them, however, I don't allow any of my
peers to 'transit' my network.
