Packet loss since 1st April - Area 14

Hi

Since midnight on 1st April, I'm seeing packet loss in area 14 on an FTTH connection. I don't imagine this is congestion or line health related, as it started at midnight. Suggesting some sort of planned maintenance work.

I've included the graphs below, showing the difference between my previous connection state on 31st March and how it looks now.

Is it possible for someone to please take a look?

Re: Packet loss since 1st April - Area 14

It also looks like the packet loss is in the upstream direction.

I can see that two of the 50 packets are lost.

When I check the logs on my home router:

Home#show log | c <WEBSERVER IP>
Number of lines which match regexp = 50

It shows a log entry for each of the 50 pings, advising that it received the ping packet and uploaded a ping reply.

Is there any hope in me trying to communicate this to your callcentre?
