Joining an IX is more complicated than just buying Internet service
and recently we had the DECIX in New York City completely crash which
took down a whole bunch of traffic.
I would rather have multiple carriers than be relying on a single IX
that I have no control over

about the same cost. In any case you are going to need the big pipes,
in case the IX goes tits up.

time to look for some 10Gbps interfaces. No way around it! I went
from 1G to several 10G interfaces now I'm pushing my carriers for
100G interfaces. Carriers like Cogeco are telling me that we are the
topic of discussion on a daily basis because we are pushing them to
upgrade their network faster than they planned. If they can't keep
up you'll be force into getting creative and getting into fiber
yourselves. It will only grow and is going faster and faster. Don't
worry about starlink! 25Mbps in a house in rural areas will be not
enough in 5 years.
