Over the past few months I have (and others too) been getting up to 90% drop in speed (I was on 900Mb and, at times, was getting 9Mb, with 100Mb not uncommon) in the evening hours (from 6pm to 12pm), with an associated increase in packet loss - peaking at 20% packet loss.
This has happened 3 times over the past few months, each time it gets fixed for a few days or weeks then the fault returns. The last time this happened I called Vodafone - yet again - and reported the fault and Vodafone were quite dismissive, almost rude, and said there's nothing wrong with my connection, so I said "Goodbye", and I'm now with Zen. Funnily the day after I started the migration to Zen, 10th September, the fault went away and did not return during my last couple of weeks with Vodafone, but my confidence in Vodafone had been damaged, and there attitude during my last call put the final nail in the coffin, so I still moved to Zen. I've now been with Zen (on there 900Mb package) for 5 days and the connection is as good as Vodafone is on a good day - no problems. My idle latency has improved a bit, from 20ms to 15ms, but otherwise everything is the same, tests on speedtest.net, thinkbroadband.com (Broadband Quality Monitor) and packetlosstest.com give similar results to what I was getting with Vodafone.
The only problem is that I need my landline and asked Zen/Vodafone to port my number to Zen; Vodafone have been dragging there heels and have yet to release my phone number to Zen - I think they hope I might come back.. Anyway, as the number has not been ported when it should have been I'm due £6.10 compensation for each day of delay - nice, but I'd rather have my phone line.
