Built not to go down.
A charge that fails is a lost sale. That's why marx is redundant end to end: multiple regions, more than one payment processor and queues that retry until delivery.

Multiple regions
We run across more than one region and more than one cloud. If one goes down, the other keeps things running.
ms
Low latency
A short path to Pix: charges created instantly and webhooks fired the moment payment lands.
HA
High availability
Replicas, failover and retrying queues. A sales spike won't take your checkout down.
N
Multiple processors
More than one payment partner behind the scenes. If a provider wobbles, we have somewhere to go.
