Red LOS light on ONT this morning. FTTP 900mbps/110mbps

So we had FTTP 900mbps/110mbps installed last year around August I believe, after being on FTTC 80mbps/20mbps for 5 or so years without so much as a shutdown/disconnect. So anyway, the FTTP Full fibre has been great since installation, getting near enough and even higher speeds than 900 on speed test apps/browsers, so very happy. Until today, I wake up, go to my PC and all the error notifications pop up that it cant sign in to things, to which I notice theres no internet on my taskbar, so I go look at adapter settings and troubleshoot to no avail, then I go to the router and I think it was just orange at that point, but I then noticed the ONT had a solid red light on the LOS one, which I've found is loss of service, so I've tried troubleshooting it, turning off/on, unplugging it for 5 minutes this and that, but nothing has worked, which I wasn't expecting because like i say, we have never had any problems with it ever really. I was going to ring BT and see if they could reset the network from there end, which was a suggestion on a BT website I think, but when I went through certain steps it just immediately came up with you need an engineer appointment blah blah blah, which again was unexpected, so I booked a time for the morning between 8am and 1pm hopefully its early on as i have a funeral to go to tomorrow, so ya, earlier the better. But honestly I'm lost on this one for once. So any suggestions would be great, and honestly i think i have tried most things we can try so far, but yeah, anything else, would be good, even if it's just to read tech info and to have a tinker, us nerds love a good tech read I believe, well I do atleast. But anyway  thankyou very much to whom ever replies, bit late tonight, but I'm twiddling my thumbs at min and probably wont try sleeping till after midnight  especially we have a BT mini hub thing they send you incase of emergency just to get you some internet while yours is down and our house walls being like 1700's era are solid stone thick walls  so this mini hub with a EE sim card is not great, I think it was running 7mbps down when I checked, and when the house is full of highend PC's that have 4k screens and a 60" 4k tv in the living room, and various other mobiles and stuff  yeah, the 7mbps dont cut it. Think it was buffering on 720p youtube earlier, so dont think anybody will be having a great experience in the house tonight.  Thanks again, and any help is good help, thankyou.

Re: Red LOS light on ONT this morning. FTTP 900mbps/110mbps

LOS , loss of signal , your ONT is not receiving a  ‘light’ signal , this is most likely a physical disconnection somewhere , it could be something that’s just affecting you ( like the splice in the CSP failing, but that’s unlikely after a year ) or something affecting others ( like a cable serving you and other damaged by others excavating in the street for example ) , either way it’s extremely unlikely that there is anything you could do yourself to fix the fault ,  even if you had specialist equipment all you could do is measure the distance to the fault ,

It also could  be your ONT is faulty , or the headend equipment is faulty , if it were the headend, it wouldn’t just be you affected, but essentially all you can do is wait until OR fix whatever the issue is, FTTP is more reliable that copper , but isn’t infallible, especially if you consider it’s not just Openreach engineers entering Openreach joint boxes and ducts
