BT have a major problem at the moment and lines which log off are unable to log back in again. Our TalkTalk services are unaffected, and lines which stay online are unaffected. This looks to be a country wide problem affecting many ISPs.
BT are aware (obviously!) and have given us notice of this outage as follows: We are aware of an issue impacting connectivity to Broadband services and are currently investigating with technical support teams. At the moment, we are unable to inform you of your specific affected circuits and services. Once root cause is established we will issue this detail promptly.
Our XML requests are going in to BT now - and very very slowly coming back out... This may be a sign that BT will start working again... However, lines which have disconnected this afternoon have not yet logged back in.
This seems to be resolved - we'll see if BT have more detail in sue course.
