RCS Partial Service Issue

Hello,

I've been having an issue with intermittent internet cut outs and suspect there may be an issue that requires an engineer callout.

Hi @shread_r 

Thanks for posting and welcome to the community.

Very sorry to hear of the broadband issues.

I can see since posting that you've spoke to the team and booked a tech visit.

Please let us know how that goes.

Best wishes.

We had the engineer visit today. Our external cables and connectors were replaced as they were corroded, but an issue was still detected by the engineer at the green street box. This has been escalated to the specialist that deals with those and I was advised this should be resolved in the next day or two.

Don’t be so hopefull mate they know exactly what’s happening and it’s all because of the telephony upgrade n revamp - technicians will not tell you , just change hub rewire stuff but from what my friend can gather who works for them the intermittent drop outs could be up until the 30th for some of us -  search google there’s a ton of people having exact same problem …. You’ll prob find it doesn’t go off once in the early hours of the morning because no one’s working on it -

had two technicians round and a rewire and it don’t do jack and it won’t do jack until they sorted everything out properly.  Trust me

they reply making it sound like it’s an individual problem on purpose so ya think it’s just you but it ain’t there tons of people and they know exactly why but they wont tell you 🥲

Hi shread_r, thanks for the message and welcome back to the forums. 

I am happy to hear that the engineer came out and resolved the cable issue. I have looked at the area and can see that there is some SNR - this is estimated to be fixed on the 26th October and the fault number is - F011019122 ^Chris.

Hi Chris_W1,

Is there a way for me to track the progress of this fault online?

Thanks for the reply @shread_r on the forums. 👋🏼

You can track the fault here, via our online checker.
Let us know if you need anything else and we'll assist.

Kind regards,
Ilyas.

Hi Ilyas_Y,

I can't see any way to track an individual fault using a fault number on the link you provided. All I can see is the button to check my own service status, which is incapable of detecting my RCS Partial Service and SYNC Timing Synchronization failure errors which are still happening.

I was informed during my engineer visit that a secondary fix at the green box was required to resolve my issue, which would happen within 48 hours of that first visit. Has the issue not been addressed? Is it more serious than previously thought? How long will I have to wait before these issues are resolved?

With an SNR outage we wouldn't send a tech out as its an area issue not individual . 

From looking at it I can see this has been extended to the 31st Oct sorry.

Is there a way I can track the progress of the fix online without coming here and waiting for a response?

This was supposed to be fixed within two days of my original engineer visit.
