Maintenance notice: hosting service improvements

In the interests of always improving our customer experience, it's almost time to start making those improvements to our hosting services. 

What are we doing?

This work is intended to make sure our infrastructure as a service provider stays up-to-date with the current technologies, and keeps our service robust and healthy. For a full explanation of what we're doing and why, refer to this article: Improving our hosting services.

When are we doing it?

We're going to begin these changes in May, starting with customers in the European regions (EMEA), before moving on to clients in the Asia-Pacific (APJ) region in October, and then finishing up early next year with everyone in North America (NA). 

Here are the currently planned windows for this maintenance:




Europe, Middle East, and Africa - Completed!

May 8-11, 2018

May 22-25, 2018

Asia Pacific - Completed!

October 16-18, 2018

October 23-25, 2018


January 8-11, 2019

January 15-18, 2019
January 22-25, 2019

How will we communicate with you?

While our process will be similar to the recent database updates we performed, we learned a few things during the process and we're taking your feedback to heart. We'll be modifying our process slightly to try and help make things even smoother and hassle-free.

Well ahead of time, we'll provide you with a specific maintenance window during which you can expect us to implement the changes for your instance. 

Then, we will notify you again for your specific downtime - both when your service is about to go down, and again once the maintenance has been completed and your service has been restored.

Also, to help reduce confusion, we won't be posting a maintenance notice on the xMatters status page each day. (That way you won't get reminded about a maintenance window in your region that may or may not affect you.)

How will this affect you?

Within your maintenance window, you may experience up to a maximum of 30 minutes where the service is unavailable. (Most customers will experience significantly less.) During this time, notification and response processing is not guaranteed.

Please also note the following:

  • Four hours before the start of your maintenance window, we will pause all EPIC synchronization, user upload, voice recording, and archive/purge processes. (If you attempt to initiate any of these processes within this time or during the maintenance window, your changes may not be persisted.)
  • Events in progress at the time of the maintenance may be disrupted, meaning that notifications and responses may not be processed and the events may be delayed or lost.
  • Scheduled triggers or messaging will be delayed until the service is restored.
  • The IP ranges that xMatters uses will change once the maintenance on your instance is completed. If you are using IP whitelisting, you will need to update the IP ranges in your systems or you may experience further service disruptions. Client Assistance can provide you the complete list of IP ranges prior to the maintenance. For more information about IP whitelisting and why we don't actually recommend it, see this article: IP Whitelisting for xMatters On-Demand.

What will happen to your incoming events?

If an event enters the system during that brief moment your instance is offline for maintenance, one of two things will happen:

  • If it comes in through a legacy integration (using an APXML request via the Integration Agent), the event will simply be placed in the queue until the heartbeat between the Integration Agent and xMatters is restored. When the connection is reestablished, the Integration Agent will submit the events in the same order as they entered the system. 
  • If it's an Integration Agent event targeting a communication plan via REST, the request will return a 503 error (see example below) that we've set up specifically for this maintenance, instructing it to retry every ten minutes, up to three times. If another event enters the system after this, xMatters will place it in the queue for processing behind the first event, and then process them in order once the retry is successful. (This does mean that xMatters might not process the original event immediately when the service comes back online, depending on the exact timing between the 503 error, the retry interval, and the restoration of the service.) 

How do you get help?

If you have any questions about this maintenance, use our online form to submit a request to xMatters Client Assistance. Not only are our support agents always available, but they will always have access to the most up-to-date information and updates.
