Magrathea (one of our voice carriers) is currently investigating network issues, further updates to follow.
Looks like a major outage for them. This will be affecting inbound calls but some customers are still able to make calls outbound. I'm afraid Magrathea have no more information to provide on the issue at hand.
Partial service has been restored now. Magrathea are still working on this. More updates to follow...
Magrathea believe service is almost fully restored now. We'll let you know once we get the all OK.
From Magrathea: We can confirm that we have the all clear and service is fully restored. Early analysis shows the peak of the outage was between 14:20 and 15:00 with service improving rapidly after that. As soon as we have completed our analysis and have a reason for outage we will send an email with details.
