Welcome to Vodafone Community
Am just adding my details on to this as it's effecting me, it's taken me ages to figure out the issue and now can understand it.
Phil am a business customer and am trying to obtain a ticket number in relation to this issue for my own records as if this isn't resolved quickly I will be leaving.
I can't phone the call centre as they keep insisting there is nothing wrong and i must unplug everything, use the master socket etc, when i've told them there is no physical problem this is something to do with your network.
My line sync is 43Mb.
Submit a formal complaint and ask to leave penalty free. If they refuse ask for a deadlock letter (may take several weeks). VF have been denying this issue for months, so it will still be several years before they fix it. What they really want to avoid is loads of complaints of Ofcom...
If you are using chrome, there is a speedtest.com extension, so you can try for individual sites.
Two weeks ago anything going through VFs London servers got mashed. Up untill yesterday everything within the UK seemed to be working, but anything international got mashed.
Today for me, as far as I can tell on my "damaged" connection even international connections seem to be working - managed to test a 4K twitch.tv stream on my Superfast 2 which thanks to a love match between the OR cabinet and a digger is only running at 20Mbp sync, and it rand smoothly.
13 down, 16 up, so still broken for me... using Vodafone's new Basinstoke server (probably still the same London one).
Using BT Lancs I see 13.58 down and 14.40 down, so they've even managed to break a working link to Janet now....
i've put a formal complaint in - i think
Awful service, i've had enough now, was only trying to get recognition of the problem at first but the attitude i got has made me decide to leave.
P.S Anyone know why Vodafone Support say it's a DNS problem and want to change the DNS servers to Google's
Literally felt like crying at this point as every one of there support states the speed is the DNS setting.
You can try pointing them at switch routing video classes, but you are never going to convince them that DNS just provides the end-point and not the route.
What I would say though is that in general Vodafone's DNS servers are incredibly slow (try running Gibson Research's DNS bench), so there may be benefits from using other DNS servers!
I run pfsense with opendns servers, all works fine, look up times are fine.
It looks like voda use their own CDN for video, wondering if there's a problem in that network.
Congestion on Gigafast. Even multithread slow. Down 14Mbps / Up 102Mbps. Line 900/900
Super fast speed is one thing, however Twitch . tv uses less than 10 megabits /second via a 1080p source stream.
!!! HOW CAN THIS BE BROKEN FOR SO LONG !!!
Twitch.tv now streams well 1080p 60fps from EU. speed now 14Mbps
USA and Asia OK too but chat isn't loading
on the advice given by Ofcom can customers having this issues please fill out this form so that Ofcom can monitor the issue, Which could lead to Ofcom launching an investigation into the company. if the issue is not sorted within a reasonable time
Done I will lodge my complaint with Vodafone once I leave, purely for stat reasons as my 18 month contract expires three weeks today so the complaint wont be 'resolved' in their given time period but at least it will be another one to count towards the numbers of complaints made - cant wait to click on that sign me up button on another ISP...
