Christchurch, DSL, 08/09, Unplanned Outages
Due to severe weather conditions many of our copper network customers around Christchurch may experiencing a complete loss of service.
Our technicians are aware and are working to resolve this issue currently.
While I'm not aware of any outages on my line my connection has dropped from 62 Mbps down to 19Mbps with no change 24 hours later.
Not impressed....
