Postman v2 SLAs

1. What is Postman v2’s uptime?

• Postman aims to have an uptime of >99.5%. We have internal services to monitor Postman uptime 24/7. These services send alerts if the product is down to the engineer-on-call, so that we can respond as soon as possible.

• If you are unable to access Postman services and would like to check if it is due to an unplanned downtime, check our status page here.

• No, we will inform all users if there is going to be a scheduled downtime.

3. Subscribe to status updates:

• Typically, we inform users of downtime only if resolution is expected to take longer than a day, or if your campaign is directly affected.

4. How long can I expect a reply for my queries?

6. Where and when can I expect to be informed about updates to Postman?

• Whenever we make an update to the product, it will be listed on our updates page.

• We will also communicate this on our BTN Microsoft Teams channel called "WOG Channel for BTN". If you are not in this channel, please let us know by submitting this form. Note that only users with emails ending in ".gov.sg" can be added to the channel. Vendors cannot be added to the channel.

• Where a product update is significant and will affect your workflows, we will communicate this through email blasts to all users of the Postman v2 test and production environments.

• We seek your understanding that as the product is still developing and the situation remains dynamic, changes may be made along the way, and may affect your current system set-ups. As far as possible, we will try our best to communicate this to you with significant heads-up for you to make the necessary preparations.

• We apologise in advance for cases where we inform of changes in a short span of time.
