Monitoring - On March 9, Fourth will implement an update to the Customer Success Portal in alignment with enhanced security requirements.

Users will be required to log in before submitting a support ticket.

There is no expected impact to service availability or performance. Support continues to operate normally; only the login requirement for submitting a ticket is changing.

For more details — including what this means for your experience and how to create or access your portal account — please see our announcement here:

Zendesk Security Update: Sign-in Now Required for Support Requests
https://help.hotschedules.com/hc/en-us/articles/44077614528909-Zendesk-Security-Update-Sign-in-Now-Required-for-Support-Requests

Mar 06, 2026 - 21:11 UTC
Monitoring - We have been made aware of an issue where historical WFM release notes have been unintentionally sent via email to subscribed customers.

This was caused by a technical issue during a bulk update within our help center tooling. The process has now been force-stopped, and we are working to fully mitigate any remaining notifications that may still be in transit due to email delivery latency.

We sincerely apologise for the inconvenience this may have caused and appreciate your patience while this is resolved.

No action is required from customers.

You can remain subscribed to release notes and will continue to receive them as normal going forward.

Monitoring - On 1 July 2026 at approximately 13:20 BST, we became aware of an issue affecting access to the Scheduling (Labour Productivity) application for a number of customers.

The issue has now been fully resolved. As soon as it was identified, our technical teams responded immediately and began investigating. We established that the issue was related to a change within our third-party hosting provider's infrastructure and worked closely with them to restore service as quickly as possible.

Service was fully restored by 13:52 BST.

We sincerely apologise for the disruption and any inconvenience this may have caused.

A formal Root Cause Analysis (RCA) is currently being prepared, and we aim to share this within five business days.
