We are currently facing a large DDoS attack on the offsite DataCentre we use for our billing and ticketing systems, the incident is being treated as a priority 1 and we will post updates here as we get them.
We offload our billing and ticketing systems to a different DataCentre for redundancy so should our primary DataCentre be unavailable access to your billing and ticketing systems would be unaffected.
Update: This has now been mitigated and the issue resolved.
