This page provides details of on-going live changes where service disruption is expected. Planned activities include infrastructure maintenance, software and hardware upgrades and application releases. Ordinarily these activities do not result in any non-availability of the Online Services to the Client, but this cannot be guaranteed. TransUnion contacts Clients by email with at least 7 calendar days notification prior to any work anticipated to affect service availability.

TransUnion also reserves the right to apply hotfixes or emergency maintenance without providing advance notice, however, advance notice will be provided where this is reasonably possible.
