Users unable to subscribe via Slack

We have monitored the service and can confirm this has now been resolved.

The root cause of this was due to a sub-domain being missed from an improved safe list as part of our security and performance improvements. We are reviewing how sub-domains are configured for the application and adding extra QA tests in place.

Once again thank you for your patience and apologies for the disruption.

We have now identified the root cause of the issue and deployed a fix. Users will now be able to subscribe via Slack successfully.

Once again, apologies for the inconvenience this has caused.

We are investigating issues with users trying to create a new subscription via Slack. Users are getting a Page that cannot be found. We urgently investigate and will provide updates as soon as we have identified the cause.

Apologies for the inconvenience this has caused.
