DNS Advice - Site not visible on Plusnet

HI,
I am working on upgrading a website. The site was visible for a short period of time, ie the tie it took for me to upload the new layout. Unfortunately it is not  visible on any of my browsers or computers using my wifi at my home office. I can't ftp to it either, the ip for weebly (199.34.228.55.) is automatically retrieved.
The nameservers have been changed from 123-reg to the new host. The new host can view it on their servers, I can also view the site on my mobile phone service provider's web access but not when I use my phone on the home wifi network. The only thing I have not tried is taking my computer to a different location using a different isp.
Does anyone have any suggestions?
Thanks in advance.
Andrew

Re: DNS Advice - Site not visible on Plusnet

When you make a DNS change, it can take a while for that change to propagate.

DNS has a setting called "Time to Live" (TTL): this tells DNS servers how long it is allowed to cache the setting for. Typically, this is set to 24 hours (and your DNS provider doesn't give you the ability to change it).... so any DNS changes can take up to 24 hours to become live.

Re: DNS Advice - Site not visible on Plusnet

Thanks for your reply. Name servers are pointing to sitehq.co.uk's hosting, not through plusnet.

Thanks for your reply Paul.
I uploded the site a couple of weeks ago actually. I can see the new site on my mobile phone if I use the Vodafone network but not if I use my home wifi. My hosts at Sitehq can see the site too. Plusnt say they are not blocking anything. The only thing I have not tried is using my laptop somewhere else on someone else's ISP.

I meant your local DNS server, not the website

Re: DNS Advice - Site not visible on Plusnet

Are you able to let us know the domain name in question?

The domain is www.ericwatsonfs.co.uk. IfI use a proxy server it is also visible.

Re: DNS Advice - Site not visible on Plusnet

It's visible from our internal network here and also doing a lookup on both Google DNS and our DNS server shows the domain points to the same IP:

 

nslookup ericwatsonfs.co.uk 212.159.6.9
Server:  cdns01.plus.net
Address:  212.159.6.9

Non-authoritative answer:
Name:    ericwatsonfs.co.uk
Address:  91.224.108.20


nslookup ericwatsonfs.co.uk 8.8.8.8
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    ericwatsonfs.co.uk
Address:  91.224.108.20

 

So it doesn't appear to be a DNS issue from what I can see there.

Re: DNS Advice - Site not visible on Plusnet

I just ran a full resolve from dns.squish.net and it resolved (from the root servers) ok, although did seem to take a while.

Technically:

www.ericwatsonfs.co.uk has a CNAME record, which points to ericwatsonfs.co.uk

ericwatsonfs.co.uk has an A record which points to 91.224.108.20

(both the above have a TTL of 14400 seconds = 4 hours)

The nameservers for your domain are ns.123-reg.co.uk and ns2.123-reg.co.uk

Re: DNS Advice - Site not visible on Plusnet

I just did a full resolve from root at dns.squish.net, and it worked, as in the previous post.

 

However, I just did an nslookup from my pc here, using 8.8.8.8 as well as the same 2 plusnet DNS servers (they are the ones picked up by my router) that Chris used, and the Plusnet DNS FAILED to resolve:

 

> server 8.8.8.8
Default Server:  google-public-dns-a.google
Address:  8.8.8.8

> ericwatsonfs.co.uk
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
Name:    ericwatsonfs.co.uk
Address:  91.224.108.20

> server 212.159.6.10
Default Server:  cdns02.plus.net
Address:  212.159.6.10

> ericwatsonfs.co.uk
Server:  cdns02.plus.net
Address:  212.159.6.10

Name:    ericwatsonfs.co.uk

> server 212.159.6.9
Default Server:  cdns01.plus.net
Address:  212.159.6.9

> ericwatsonfs.co.uk
Server:  cdns01.plus.net
Address:  212.159.6.9

Name:    ericwatsonfs.co.uk


(Worth adding for completeness that - using 8.8.8.8 -  www.ericwatsonfs.co.uk returns a CNAME record, pointing to ericwatsonfs.co.uk)

So Chris do you have any suggestions?
I am able to see other sites hosted on sitehq and actually ftp to them too.

Re: DNS Advice - Site not visible on Plusnet

I can confirm with 8.8.8.8 it's fine, with plusnet dns it's a no go!
