I'm a longstanding Origin customer, having joined many years ago when they were Plusnet resellers. The Plusnet resold service was flawless as you'd expect, but nowadays Origin's broadband service is delivered via their self-owned network.
I stuck with Origin during their difficult migration period, where they moved us customers from the resold Plusnet service over to their own network (powered by TalkTalk Wholesale tails). The migration itself was wholly unexpected, but only required new PPP auth details to get back online. The perhaps 2-3 weeks that followed were troublesome as Origin found their feet, but I stuck it out.
Fast forward to many months later and I'm a happy Origin customer. Their network is largely problem-free and uncongested (no more or no less problematic than other major ISPs). Calling for support sometimes leads to 20 minute wait times, but it's no better or worse than Plusnet or TalkTalk in this regard. Crucially, customer/tech support gets the problem resolved.
The overall experience is largely faultless with minor quibbles. Nothing that wouldn't be expected from other ISPs. The value is amazing, and you get what you pay for plus much more.
