Everything continues to run as normal. We will now switch to our usual monitoring.
We will be working with our providers over the next few days to fully understand the impact, communicate that information to you and then decide what we can do to make sure this doesn't happen again.
Thanks again for your patience. We know this had a big impact on your service and your users.

We believe the problem is now solved by the network provider.
This morning we have manually tested the numbers affected. Before 11am roughly 50% of affected numbers were working. At roughly 11am it appears full service was restored. If you are still having any issues receiving inbound text messages then please contact us.
We will continue to monitor the situation throughout the day.
Our next steps will then be to confirm the time frame and impact during this incident. When we are confident we know what happened we will communicate that on our status page and also email it directly to those services that were affected.
Once again, we apologise for the impact this has had to your service and your users.

We've been advised by the affected mobile network that the cause of the problem with inbound text messaging has now been resolved. It is likely to take a number of hours before all inbound numbers return to full service, but I'm told by tomorrow morning all numbers should be functioning again.
We will check this first thing, and will let you know. Importantly, we'll let you know what that means for messages people attempted to send you during this disruption.
Thank you for bearing with us. I know it's rubbish, we're working hard to get things back to normal for you.

The issue with some inbound text numbers failing to receive text messages is still ongoing.
We have narrowed down the range of numbers affected and have emailed those service teams.
If you have not received an email from us then your inbound text messaging should be working correctly.
The mobile network that provides the affected inbound text numbers is still trying to resolve this issue.
We will update this page as soon as anything changes and before the end of the working day.
Thank you for your patience and we are sorry for the impact this is having for your users.

The issue with some inbound text numbers failing to receive text messages is still ongoing. We have escalated this to the phone network who provide us those inbound text numbers and they are currently trying to resolve this issue.
Apologies again and we will update you before the end of the working day.

The issue with some inbound text numbers failing to receive text messages is still ongoing. Unfortunately our inbound text message provider has so far been unable to fix this overnight. We are currently escalating this to the mobile networks.
We're very sorry for the inconvenience and impact this has caused. We know how important the ability to receive text messages is for your service.
We will update this channel as soon as we have any news, or at the very earliest in the early afternoon to confirm the issue is still ongoing.
If you have any questions then please don't hesitate to contact us via our support page - https://www.notifications.service.gov.uk/support

The issue with some inbound text numbers failing to receive text messages is still ongoing. We are still waiting on an update from the phone networks, and will post a new update first thing tomorrow morning.
We're very sorry for the inconvenience and impact this has caused to your service.

We are still seeing a problem with a proportion of our inbound text numbers failing to receive text messages. The issue appears to only be affecting certain ranges of our inbound text numbers.
This appears to be an issue at the phone network level and our text message provider is currently working on our behalf to resolve this. They have not yet been able to provide us with an estimated time in which this will be fixed.
If your service has been able to receive text messages in the past few hours then we believe you are unaffected. For services that are unable to receive text messages then it is not yet clear whether any messages that users attempt to send to you will eventually be delivered or will be lost.
We will update you as soon as we find out any further information on the impact or when we expect to have this resolved.
Apologies for the inconvenience.

We are aware of a problem with a proportion of our inbound text numbers failing to receive text messages.
We believe this may be a problem with our inbound text message provider and the phone networks. We are currently in contact with our provider to resolve this. We will update you with further details shortly.
