Hi all. I'm having trouble with short-term drop-outs on my fibre WAN connection. I created a simple connection monitor in Python (attachment 1). Attachment 2 shows the results over the last 3 days.

1. Do I have a reliable method of monitoring the connection?

2. I have difficulty working out why a down/up pair can have the same time (to within 1 second) on many occasions.

BT Openreach were involved a few days ago but thought the problem sorted.

Comments gratefully received before I re-open a fault ticket.

Graeme
