Hosted Services Upgrade: Customer Information Hub
This page brings together the key information about the planned upgrade to the hosting environment that supports your Causeway services. We will continue to update this page as the work progresses, and you can revisit it at any time for the latest details.
Last updated 16th December 2025
What is happening?
We are upgrading the underlying infrastructure that supports a number of Causeway hosted products. This work will move services to a more modern, resilient and scalable environment.
The products themselves will not change, but some customers may need to update parts of their technical configuration to ensure their services continue to connect as expected.
When will the migration take place?
The upgrade will begin early in the new year and will run in phases, with all activity expected to complete by the end of February 2026.
As part of this work, there will be planned outages while services are migrated. We will provide advance notice of any outage windows that apply to your organisation.
We will continue to keep you informed as the programme progresses, and this page will be updated with specific timings as each phase is confirmed.
How will this impact you?
There will be planned outages scheduled as services are moved to the new environment. To ensure continuity, there will be a few checks for you to complete both ahead of the upgrade and once your services have been migrated. You can find guidance on what is needed on this page, and we'll continue to keep you informed throughout the programme.
- Causeway Mobile Platform - Scheduled for early January
- Causeway Estimating - Scheduled for mid-January
- Causeway Project Accounting (CPA) and CPA Services (including CFA and Vision) - Scheduled for phased customer batches starting from mid-January

Check how your systems connect to Causeway services
Please use DNS names wherever possible rather than hardcoded IP addresses.
Update any firewall rules or IP allow-listing
If your systems currently use the old IP address 82.196.234.192/26 , then your IT team will need to update this with the new range: 77.111.227.64/26 ahead of the move.
To minimise disruption, you can add the new range in advance. If you require a specific product IP address rather than the full range, please contact the Causeway Support Team and they will provide the details you need.
Prepare to test your services once the work is complete
Especially if they use FTP, SMTP or RDP connections.
Ensure your IT team is aware of the planned change
Please make sure they are ready to update any configurations that rely on IP-based rules.

Stronger resilience
The upgraded environment is designed to support consistent service availability and reduce the likelihood of disruption.
Capacity to grow
It offers greater flexibility so that services can scale smoothly as usage increases or as organisations expand their use of Causeway solutions.
Enhanced security controls
Modernised, built-in security measures provide strong, consistent protection aligned with recognised standards such as ISO27001 and Cyber Essentials Plus.
Performance improvements
More efficient use of resources supports smoother, more responsive day-to-day performance across hosted applications.
Ready for future developments
The upgrade allows us to deliver new features, improvements and integrations more easily as our solutions continue to evolve.
