checked and no faults listed

[Client62]

Call in your fault,  folks living close to you may not have spotted this yet.

[linwelin]

What makes you think it is an area fault? 

[Client62]

The loss of all upstream channels is typical of a fault in a local street cabinet.

[Adri_G]

Please, confirm this and we're eager to assist.

Internet still has not gone off since, but i don't know if it is an issue or not that it is not reporting any upload stats, you tell me lol?
