I’m a bit struck in what to do next. Our internet went off yesterday I rang the isp they said everything was fine they end. So I thought the problem was our network, after 2 hours of messing around I rang the ISP again. They said our subnet **.**.**.**/28, during a change request for one of our customers , he has mistakenly advertised it to our core this afternoon causing you loosing you connection. We apologize of any inconvenient caused. 5 mins lately it was working, Has anyone been in the same situation ?
