Very high latency issue

Around the start of the lockdown I've started having occasional days with very bad Latency, most multiplayer games have become unplayable and sometimes even youtube/spotify stops or the quality would go potato breifly. But recently, the last two week its constant pings are flying allover the place, from lows of 4ms to highs of almost 4000ms.

Re: Very high latency issue

Your downstream levels are all far too low and will require a visit to correct them.  You could try calling support, or wait for a VM person to find this and take pity on you.

Re: Very high latency issue

I'm hoping someone from their team can find this hand help out, Looks like a common issue with the VM network ATM and if they cant fix it then hopefully they will let me end the contract so I can get FTTC installed, working over remote desktop for work is pushing me over the insanity line 🙂 Call centre is never that helpful, especially if I need to provide them the above info.

Re: Very high latency issue

Had a chat within someone on the phone, so I'm affected by a fault that's going to resolved once an upgrade has taken place on the 5th of August, hopefully 😞

Re: Very high latency issue

Been almost a week since posting, and I have called in to have this checked, I was told that a "Fault" existed and I was affected by it... No mention of the fault id and the email/text message that was meant to be sent with the fault so I could keep an eye on it never arrived. 😞

Any chance someone from the forum team can send me a PM so I can get more info on whats going on?

 

Ta,

Re: Very high latency issue

Hello pbgben,

 

Sorry to hear about your latency issue. I've tried to find your details but I'm unable to so I'll send you a Private Message to see what's going on. Please reply back to it 🙂

 

Thanks,

 

Lisa
