Here's everything you need to know: 

network--overlay
What is happening?

We are upgrading the underlying infrastructure that supports a number of Causeway products. These updates will ensure our services continue to operate on a more modern, resilient and scalable foundation.

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.

calendar
When will the upgrade take place?

The upgrade will begin in January 2026 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 we carry out the necessary upgrades to our infrastructure. 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.

There will be planned outages scheduled while we carry out the infrastructure upgrade. To ensure continuity, there will be a few checks for you to complete both ahead of the upgrade and once your services are running on the enhanced environment.

What to check and how to prepare

To ensure your services continue running smoothly throughout this change, there are a few checks to complete on your side.

1
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.

2
Check how your systems connect to Causeway services

 Please use DNS names wherever possible rather than hardcoded IP addresses. 

3
Update any firewall rules or IP allow-listing

If your systems currently use the old IP address range of 82.196.234.192/26 , then your IT team will need to update both inbound and outbound IP ranges with the new range: 77.111.227.64/26 ahead of the change.

To minimise disruption, you can add the new range in advance, but please do not remove the old ranges until after the changes have been applied. 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.

4
Be available during the change window

To confirm service continuity and make us aware of any issues, please contact the Causeway Support Team so that we can resolve them quickly.

Why this change is important

This upgrade is part of our ongoing work to ensure Causeway’s hosted services remain reliable, secure and ready for future growth. It strengthens the environment behind our products and supports the evolving needs of the organisations that use them.

Frequently asked questions

What do I need to know after the upgrades have taken place?*
Make sure the new Causeway IP address range has been added to your firewall or security allow-list.

If your organisation uses IP allow-listing, both the new IP range and the existing (old) IP range should remain active at this stage.

Please do not remove the previous IP address range until we confirm it’s safe to do so. Removing it too early may affect access to other Causeway products or services.

We’ll contact you again at the end of the programme to confirm when you can safely remove the old IP address range and complete the final housekeeping steps.

Will our services be unavailable during the upgrade?

Yes. There will be planned outages while services are updated. We will provide advance notice of any outage windows that apply to your organisation, and this page will also be kept up to date with the latest information as the programme progresses.

 

Do I need to make any changes, and how do I know if they apply to my organisation?

Some organisations will need to review their connection setup, including DNS usage, fixed IP addresses, allow-listing or firewall rules. Your internal IT team should be able to confirm whether any of these apply to you. The guidance above outlines what to check, and once your services are operating on the upgraded environment, we recommend a brief connectivity test, particularly for integrations such as FTP, SMTP or RDP. If you need any additional support, please don’t hesitate to contact the Causeway Support Team.

Can we whitelist the full IP range, and what if we need a specific product IP address?

Yes, you can allow the full new IP range 77.111.227.64/26 ahead of the upgrade, and doing so will help minimise any potential access issues. If you need the exact IP address used by a specific product rather than the full range, please contact the Causeway Support Team and we will provide this information.

What should we do if the right people in our organisation aren’t receiving your email updates?

It’s important that your internal IT team are aware of these changes and can support with the required checks. If anyone who needs this information isn’t receiving our updates, please ask them to contact marketing@causeway.com so we can ensure they are added to the correct mailing list.

When will our organisation be scheduled for the upgrade?

The upgrade will be scheduled by product and, for some services, in customer-specific batches. We will continue to communicate with you so you know what to expect and when. This page will also be kept up to date as timings are confirmed.

Will this change anything about how our products work or how we access them?

No. This work does not change product features, functionality or data. Access routes will remain the same unless your organisation uses fixed IP allow-listing, in which case we will guide you through any required updates.

If I experience access issues after the upgrade, what should I do?

If you experience access issues once the upgrade is complete, we recommend first checking with your internal IT team to confirm that any required allow-listing or firewall updates have been applied. If access remains unavailable after this check, please raise a ticket with the Causeway Support Team so we can investigate and resolve the issue as quickly as possible.

Why is this upgrade happening?

This upgrade is an important step in strengthening the hosting environment behind Causeway’s solutions. It allows us to continue delivering reliable, secure and high-performing services as organisations grow and their needs evolve. It also positions us to introduce improvements and new capabilities more easily in the future. By investing in this upgrade now, we’re ensuring that the services you rely on remain robust today and are ready for the opportunities ahead.
