1. Introduction: The Burst SMS difference

The purpose of this document is to demonstrate our commitment to providing our Services with the highest possible uptime, speed, security and compliance. We have extremely high standards when it comes to the reliability and connectivity of our services. We exist purely to deliver and report on your messages whenever and wherever you need, and we stand by our ability to deliver on this commitment. Our honesty and transparency about our service commitments & guarantees has been one of the underlying factors for our success. Loose promises are one thing: commitment, transparency and delivery are entirely another. As a part of our transparency, Burst SMS publishes the historical averages of our service delivery. You can see what we have delivered to our valued clients over the years, and can see why we have earned our place amongst the top messaging companies in our operating regions.

4. Support Commitments and SLA's

Service Failure Lifecycle:

Should you experience any problems with our services, you must report the failure directly to us as soon as possible.

As soon as we receive any reported downtime from you, we will perform an initial investigation and respond to you with our findings:

(a) advising whether or not we can identify a failure resulting from the Burst SMS platform;

(b) and if the failure is found to be within the Burst SMS platform, we will advise of the severity of the failure and the time estimated to rectify it.

Burst SMS will use all reasonable measures to rectify any failure in accordance with our failure correction times as detailed in Priority & Response Times:

A failure will only be considered rectified once we determine that the failure has been fixed and we have let you know.

  • If we determine that a failure has occurred because of the network operator failing to send or receive SMS messages, we will work with the relevant network operator to correct any problems encountered by their platform.
  • We will provide regular and ongoing updates over the course of any downtime, until resolution and service restoration.
  • We will provide an Incident Report for any material Service Failure.
  • We will rigorously analyse all Services failures to learn, and to the maximum extent possible, put in place safeguards, patches, fixes or procedures to mitigate the risk of a similar repeat event.

When such a scheduled maintenance is required, we will ensure we provide you with at least 48 hours notice, and;

We promise to conduct any maintenance required in a manner that will minimise any potentially adverse impact upon our ability to provide services.

In the event that we are required to undertake un-scheduled maintenance, Burst SMS will provide you with as much notice as we are reasonably able to provide, detailing:

(a) the expected duration of the un-scheduled maintenance

(b) the likelihood of any adverse effect such unscheduled maintenance may have on our services
