I believe so.
Within minutes of receiving an email from this committee inviting me to appear, my home Internet just stopped working, specifically for my laptop. I was still able to access the Internet via my phone, my iPad or other devices, but my computer itself would not connect to the home Wi-Fi.
This is not the first incident of it occurring. There is a pattern that when I receive emails from MPs' offices or committees, my home Internet or my devices encounter technological difficulties.
