When P(payment provider outage) x (expected lost revenue in case of outage) > (costs of implementing and maintaining an independent alternative payment processor and automatic failover), then hoping for the best and writing a comment about pain in case of outage is still the best strategy.

Lets say it takes 2 engineers 3 months to build an another payment processor + failover, at $120k salary + 40k in benefits and taxes a year a piece.

stipes SLA was 99.980% uptime for the last 90 days

0.02% * revLoss > 160k * 2 * .25/year

OP's app would have to be earning 400mm a year. Not likely but possible.

400 million a year if all revenue comes from impulsive people that won't simply try again an hour later.
