Worth switching from bt fttc?

Hi all,

Just having a look around at my options of changing from BT fttc.
How's the speeds on Zen's 80 MB fttc? also some trace routes to bbc.co.uk would be great.

Many Thanks!

Ping times are typically around 5ms. This line syncs at 80/20 and has an attainable rate of well over 100 down. I regard this as pretty much a best case scenario.

I can't do a download speed test as I'm not on site at the moment.

way better than my ping times

The ping times went up when i moved to FTTC, always get approx 16ms on the first wan hop

Worth checking if interleaving has been turned on by DLM, this affects latency.

Also depends how far you are physically from the POP, and whose backhaul you're using. For example, if you're quite a way from Manchester on BT's backhaul and interleaved, you times could be normal.

Caffn8me *could* have the perfect scenario. FAST path, close to London POP, and using Zen's backhaul as she states.

Cheers,

I have another perfect scenario today; a new installation in Chiswick.

I'm getting 80/20 sync with pings to www.bbc.co.uk averaging 5ms again.

This is with a Draytek 2860 router and no Openreach modem. I believe Chiswick is on Zen backhaul.

Zen Unlimited fibre 2 from Cornwall.
Love the service.

There are two things that can consistently make bad pings.

1) interleaving. Your line would be the same with Zen, Infinity or any other ISP; they would all have the same interleaving. You can see interleaving if the first hop (line 2 of tracert) is more then 7ms or so.

2) bad internal routing. This will differ between ISPs. I suffer with BT as my routing goes Winchester->Sheffield->London before leaving BT, adding about 9ms to ping times. I hope that Zen users would not see this. My bbc ping is around 20ms. Was around 30ms when I had interleaving.

Some people on Infinity have everything OK and get 6ms ping times.

Not nescerceraly correct ,As it depends on where in the country you are, as well as the data transit provider used, where i live 12-13ms is around the lowest latency possible on (Fast path)

Athough those who live close to a POP be that BT's or other ISP's will alway fair better on the latency front, it's a post code lottery pretty much
