IPitomy Redundant Infrastructure
IPitomy uses the AWS Global Cloud Infrastructure to host our Global VoIP Network Services and our hosted
business voice services — the industry's most extensive routing, peering, and security capabilities.
The AWS Cloud operates 38 Availability Zones within 14 geographic Regions around the world, with nine
more Availability Zones and four more Regions coming online throughout the next year.
IPitomy has facilities hosted on the US East Coast and the US West Coast. Our systems are hosted on a high
availability platforms as well as redundant infrastructure on both coasts.

AWS Regions and Availability Zones
The IPitomy Cloud infrastructure is built around Regions and Availability Zones (“AZs”). A Region is a
physical location in the world where we have multiple Availability Zones. Availability Zones consist of
one or more discrete data centers, each with redundant power, networking and connectivity, housed in
separate facilities. These Availability Zones offer the ability to operate production applications and
databases which are more highly available, fault tolerant and scalable than would be possible from a
single data center. The AWS Cloud operates 38 Availability Zones within 14 geographic Regions around
the world.

High Availability Through Multiple Availability Zones
Unlike virtually every other technology infrastructure provider, each AWS Region has multiple
Availability Zones and data centers. As we’ve learned from running the leading cloud infrastructure
technology platform, customers who care about the availability and performance of their services want
to deploy these services across multiple Availability Zones in the same region for fault tolerance and low
latency. Availability Zones are connected to each other with fast, private fiber-optic networking,
enabling IPitomy VoIP Services to automatically fail-over between Availability Zones without
