Good internet is like good coffee.

Reasons I use zen:
* static IPs and decent latency/ping. I host servers
* IPv6 is available (when you ask them for it)
* decent overall service with high uptime, without much congestion (ideally none) during different times of day
* no censorship. they don't block sites/ports. they allow traffic to flow.
* a very freedom/privacy friendly AUP

Most ISPs are like your typical instant coffee. It's 60-70% purity, and they
don't care about you. They only want their money, and they make it as cheap
and shit as possible to cut costs and compete with others.

A&A is more like pure, squeezed coffee. It's 99.8% pure, and it's black. They
charge 10x as much, but you get what you pay for, and you get the best possible
customer service. They even give you the squeezer and all the tools, and help
you learn how to use them.

Zen is still almost pure. They're still very good, better than most, 2nd only
to a&a. Theirs is 96% pure. It's good enough for almost everyone, unless you're
a snob, and it's much cheaper to buy (while still being a bit more
expensive than everything else).

I drink coffee all day, while writing code and pushing
code to git repositories using my Zen internet connection, while chatting on
IRC. I host the website for one of my projects on a Zen VDSL line.

I was previously using a&a, which I still think is the best ISP. However, Zen
now provides IPv6 (if you ask for it) and always provided static IPs and subnets
like a&a. Their customer service is still decent, and they provide more or less
the same features, while also providing unlimited download usage and being a
bit cheaper.

One thing I have noticed is that Zen does sometimes drop in speed, but not by
much. This is one of the reasons why a&a costs more (they buy more lines and
aggressively weed out all congestion, when possible).

Overall, I'm happy with Zen. It's not the best, but it's reasonably priced
and better than almost everything else, now with IPv6 capability. I'm using
a router on it that I set up myself with libreCMC, instead of the router that
Zen provided.

I also switched the ISP at my parents house over to Zen, and they're happy with it.

The service that I use is "unlimited fibre 1" (40/10 VDSL). If you're in one of the few good areas of the UK, they also provide FTTP but I can't get that.
