Thanks for your post and welcome to the Community Forums, Amaury,
Sorry to hear that you have been having connection issues. How has things been since your post? I have run a remote diagnostic and have not been able to identify any issues with your connection.
We can also provide online broadband help here: https://www.virginmedia.com/help/services-support/broadband
Let us know if you need any further help.
The incident was fixed after a couple of hours, it must have been wider than just us as I did get a message from Virgin about this affecting the area. We were able to get online with our mobile hot-spot for the time the line was down.
