Internxt offers 99.99% service availability and 99.999999999% data durability as per our SLA. We make use of erasure coding and data replication, alongside other advanced mechanisms. These are some of the mechanisms we have in place:
Data is partitioned into fragments and distributed across multiple storage nodes. This allows for "11 nines" ($99.999999999%) of durability.
We make use of erasure coding to ensure that even if multiple disks or an entire server rack fails, the data can be reconstructed.
