Good afternoon, this week the owner of the room I am renting installed your equipment, and after that many clients began to complain that the sites they need access to are not opening. We are engaged in cafes / coworking and it is very important for us that when a person comes, everything works for him, we collected from whom we could sites that do not open, here is a list:
https://www.spotify.com/
https://www.zillow.com/
https://www.boredpanda.com/
https://www.thesun.co.uk/
https://1x-rate.com/
https://www.change.org/
Tell me what it might be and how we could fix it? Who should be called or what should be done?
