Every night my speed drops from around 77 Mbps to around 1/2 Mbps. Connection is absolutely fine during the day, so positive this is some kind of contention/throttling issue. Can anyone from VM advise on this please?
Slow speeds at peak times (typically 4pm-11pm weekdays and weekends) but full speed at off peak times is normally a symptom of high utilisation/contention in your area.
Somebody from the VM forum team should be along in a few days (up to a week) to check your connection and can confirm if there is a known issue with your segment of the network. If that is the case they should provide a fault reference and pass your details onto another team who should inform you about your credit options for the lack of service via a PM. They should also be able to provide a review date for the fault. Note that it is a review date not an expected fix date and some customers affected by this kind of issue have been waiting over a year for a fix.
