Re: FTTP/FTTH Vodafone Gigafast High Ping


[re: max1486] [link to this post]
 
FTTC sync speed is not a reliable indicator

e.g. 20 Mbps sync here and pinging our servers over an IDNet connection at 9ms

8 to 8.5ms to the first hop.

The real variable for FTTC is the depth of interleaving applied (i.e. error correction).

Not expecting any decrease when FTTP rolls around, maybe 1ms.

Re: FTTP/FTTH Vodafone Gigafast High Ping


[re: epyon] [link to this post]
 
I've tested the closest one to where I physically live.

Closest server is Vodafone UK - Watford and still showing 15ms.

If I manually change the server to Vodafone UK - Manchester, I get 8-9ms ping.

I'm in Milton Keynes.


I've been comparing BT and Vodafone connections on Rocket League.

BT connected to ASUS RT-AC68U. Wired to PS4 only.

Vodafone connected to ASUS RT-AC86U. Wired to PC only.

Rocket League supports cross-platform, so I created a private match on PC and invited myself to my PS4. One of the game shows that PS4 (BT) gets around 12ms whilst PC (Vodafone) gets around 20ms. They're on the same game server as well.



What's the average ping you're getting at the moment?

The difference in pings between both providers is negligable and even then online gaming has balancing measures in place so those with the lowest ping are not at a competitive advantage to those with higher pings. Vodafone routes much of its traffic through Manchester because they have a large office there (former C&W building).

I'm getting FTTP installed next month, I'm not expecting a massive change in latency, if any at all .

They are routing your line via Manchester.


So for the majority of connections you make are going from Milton Keynes to Manchester, then to London (then onwards to the test of the world if not hosted in London.

Your friend with the lower ping is being routed direct to London.

So you have the added latency of all your traffic going up to Manchester and back down to London.
There's isn't a whole lot hosted in Manchester.

Post the results of a tracert to a couple addresses, it might show in the 1st couple hops where the traffic is going.

Get your friend to do the same if possible.

Ideally Vodafone get the routing changed as going via Manchester makes no sense.

You're totally right. I knew it.

Why would Vodafone route my line to Manchester though? Is this a rare case or?

My friend will do the trace route tomorrow afternoon, so I will share it with you all on here. I'm pretty sure his line is routed to London because his pings on online games are identical to my BT. My BT line is definitely routed to London.

Also, I will give a call to Vodafone Technical Team again and ask to be transferred to someone who knows what I am talking about (hopefully).


As requested, here are the results of tracert (CoD Warzone on PS4). I've tested on 2 different UK servers on the same game. I've also used BT connection on 2nd ASUS router for comparison, then did the tracert on 2nd PC connected to BT. All on wired connection only.


Warzone Server 1 on Vodafone: https://i.imgur.com/rOSJ3Vk.png

Warzone Server 2 on Vodafone: https://i.imgur.com/OfBJPel.png

For those wondering how I got the IP addresses of Warzone's servers, I use a third-party software from PC to 'sniff' any IP addresses including game servers on PS4.

I wouldn't say it's rare, just unfortunate. I'd say it's incredibly unlikely the people on the phone will be able to help unless they can raise directly to their network admin team. I wish you luck though!

Hi all again,

Some of you have asked me to share the results of my friend's tracert. We have used the exact same IP addresses. It appears that his (lets call him Brad) line is being routed to Slough which is only 20 miles away from London whereas my line is being routed to Manchester. This explains why he gets much lower pings on online video games whereas mine is almost doubled.

We both live in Milton Keynes and we're 10 minutes drive away from each other.


The results:

Brad's tracert 151.101.0.81 (bbc.co.uk): https://i.imgur.com/3FLCKOs.jpg

My tracert 151.101.0.81 (bbc.co.uk): https://i.imgur.com/aQUJ6Gf.jpg

My tracert 8.8.8.8 (dns.google): https://i.imgur.com/DJZigPh.jpg

Brad's tracert 78.129.201.32 (CoD Warzone): https://i.imgur.com/kj1z9zh.jpg

My tracert 78.129.201.32 (CoD Warzone): https://i.imgur.com/yivoPbL.jpg


Contacted Vodafone today to be told that their 3rd line support team is only open on Monday - Friday. They gave me a reference number so I can call directly to 3rd line team without having to explain everything again tomorrow Monday.

Also, I want to say thank you all for your posts smile

It is odd that you seem to be being routed via Manchester. But BT customers are routed via London, wherever they live. So those in the north like me don’t get good pings.

Did you ever get this sorted out? My Gigafast line (also in MK) has started routing up to Manchester as well -

Cant be sure when this started happening but can't be more than a few weeks. I tried restarting the ONT and router but no change...

I'd be very careful about assuming that 1.1.1.1 is supposed to be routed through London. Usually that's the case but sometimes Cloudflare re-routes entire data centres (due to outages or for maintenance). The whole of Cloudflare's UK data centres were re-routed through Amsterdam the other day and traceroutes to 1.1.1.1 on BT are still showing up as routed via Amsterdam for me even though Cloudflare's UK data centres are now operational again.
