⚠️ Service Disruption – Mastdata
We are currently experiencing a major service outage affecting Mastdata (mastdata.com).
This is due to a widespread fibre network failure between Sheffield and London, which is impacting upstream connectivity provided via our infrastructure partner, Hyperslice.
Their status page confirms that a primary fibre route has been severed near Sheffield, with engineers actively working on restoration:

As a result, access to Mastdata services may be unavailable or degraded.
We are monitoring the situation closely and will restore full service as soon as connectivity is recovered.
We sincerely apologise for the disruption and appreciate your patience.
