Yeah I know but best to show as much detail as possible, as they can't reproduce the issue locally.

Re: Plusnet Hub one router issue

I'm seeing the same issue, my router is cycling through four IP addresses...

 

2000-01-01 00:01:39 SNTP Unable to contact server: 212.159.13.49
2000-01-01 00:07:24 SNTP Unable to contact server: 212.159.13.50
2000-01-01 00:13:10 SNTP Unable to contact server: 212.159.6.9
2000-01-01 00:18:55 SNTP Unable to contact server: 212.159.6.10

You completely miss the point - pings add zero value here.  So "as much detail as possible" does not help in the context of the issue.  I am sure that when the covers are taken off this, its going to be the back haul network or the gateway the individual users are connected to.

If you want to add value, give the A.B.C.0 part of your IP address and the gateway you connect into - see http://usertools.plus.net/@gateway/

Re: Plusnet Hub one router issue

In advance of the PN guys getting on to this, can people reporting this issue please identify the A.B.C.0 part of their IP addresses and the gateway they are connected to.

Posts showing successful pings and failed NTP connections or router screen shots do not convey any context which is going to help the tech guys profile those for whom this is failing distinctly from those of us for which it works.

NTP is not broken - it would though appear that for some the access to the NTP server (or the response there from) is somehow broken.  The IP addresses being pinged are virtual IP addresses, behind which their are multiple DNS / NTP services in different data centres.  Hence the need for a context to those having this issue.

Re: Plusnet Hub one router issue

I assume this is what you're asking for? 

 

core2-hu0-18-0-0.southbank.ukcore.bt.net (62.172.103.24)

It does say it cannot identify my gateway.

Re: Plusnet Hub one router issue

Yes - Thanks - Indeed it does not help that for some gateways, the gateway tool has some missing information.  The PUG member who manages this tool (now also a SU) has been trying to obtain the additional data for a wee while.

What you have provided should mean enough though to those who will need to know,

Re: Plusnet Hub one router issue

the "Which gateway" tool for me says this ....

 

Sorry, the tool failed to identify your gateway; this does not mean that anything is wrong with your connection.
Posting the following information as a reply to the Gateway Checker Issues topic in the Community forums will help us to diagnose the problem.

Morning all. Managed to replicate this, suspect it's only affecting those connecting via certain parts of our dedicated network, particularly those that see the hop after there router time out on an outbound traceroute (which itself isn't a problem, it just indicates that you're probably on the affected route):
