Frequent disconnect today

[#1]

Hi,
I just switched to Fibre for less than 1 month and it has been very stable until tonight....
It has been 5-6 drops already in 2 hours' time.
Could you please have a look for me what's wrong, please? I hope it is because of the Exchange not underground cables....
By the way, I am using the master socket with a Filter Plate (I don't have vdsl filter to use the test socket).
Thanks in advance!
Regards,
Chong

Our tests aren't showing any obvious issues but I can see the drops.

When it next happens can you check the lights on the router/modem?
