Is anybody but me having problems with Xnet's DNS servers? I have them hard coded as per their helpdesk page :

Primary DNS: ns1.xnet.co.nz or 58.28.4.2

Secondary DNS:ns2.xnet.co.nz or 58.28.6.2

I did notice a Chorus van across the road this morning... /me sighes but can't see how they could possibly effect Xnet's DNS servers...

Like you wouldn't believe., google will load, google won't load. msn will sign in, msn won't sign in. When stuff does load it's slower than a 56 k modem would be.

PAINFUL..

Glad I'm not alone. Maybe the others can't get on to complain..

@CYaBro
ok, well that's strange... I would have thought that packet loss would be a problem for all Xnet users.

Can I ask what DNS servers you using?
What are pings / tracerts to the DNS servers like?

I called mum from a mates place today to try to get her to find the vodafone/ihug dialup number so that my friend could dialup on my get3 account till orcon get his dsl provisioned - anyway, things were not loading at all, even google came back not found - but msn was working just fine, so it may coincide with the time that you had the problems - about 2-3pm I would say, possibly a bit later then that.

Good thing the nice neighbour was kind enough to be operating a public hotspot so we could get on and find it, but with that available there is little reason to get the dialup number.

I've been having weird problems all night, but I just installed a new laptop with Windows 7 (I have another two machines working at home with Win7) and thought it was just a problem with that.

I find the first DNS request seems to fail/timeout etc but the second try works fine.

No problem at all, except my modem locked up once last night which happens every 1 to 2 weeks.

I nearly posted last night but didnt as it seemed to 'come right'.
Their DNS was crap last night. I got home about 8pm and had no DNS service at all from Xnets NS until nearly 11 by which time i was heading for bed.
Was only able to surf at all by manually specifiying third party NS in my boxen.

Tested from outside of Xnet I was also seeing poor reliability, so i nail DNS entirely for the problem; i've noticed there's been lots of DNS delays with Xnet (slow to resolve web addresses) which is negatively impacting on performance, despite HTTP requests themselves often working fine once the address has resolved.

Oh and nice that their helpdesk shut at 8... :\

This would be me...

BlakJak: i've noticed there's been lots of DNS delays with Xnet (slow to resolve web addresses) which is negatively impacting on performance, despite HTTP requests themselves often working fine once the address has resolved.

Ditto - it got bad enough that I switched to opendns.com, which did improve the situation.

I have been having problems with loading web pages recently too. I occasionally get one of those "Page not loading" messages when I try loading a webpage. I do not think I was having this problem before Feburary. If something is happending with the xnet DNS servers that would explain why occasionally my web pages do not load.

Interesting, I've had no issues resolving DNS with the Xnet DNS servers lately.

In saying that I've just tested and are seeing packet loss to ns1.xnet.co.nz and ns2.xnet.co.nz currently:

--- ns1.xnet.co.nz ping statistics ---
75 packets transmitted, 71 packets received, 5% packet loss

Tested twice to make sure:

--- ns1.xnet.co.nz ping statistics ---
76 packets transmitted, 67 packets received, 11% packet loss

Whereas seeing no packet loss to xnet.co.nz:

--- xnet.co.nz ping statistics ---
68 packets transmitted, 68 packets received, 0% packet loss

I do run a caching DNS server here on my network so maybe thats caching the good results so I don't have problems resolving addresses that have been cached.

Yes I concur I have been experiencing infrequent packet loss [ping timeouts] on both Xnet DNS severs the last couple of days but no such issue on the OpenDNS servers

There is definately something going wrong with their [Xnet] DNS servers maybe intermittant DOS attack ?

I hope this does not go on and they get it resolved ASAP and not take for ever like they did with their recent severe mail problems. I call them Monday

Lol yer I am still having the same problem with the dns servers timing out on me. Probably part of one of their "cost-reduction-schemes" and "profit maximisation schemes" that have resulted in them ceasing to increase supply of dns server capactiy as old dns server stuff breaks and as new customers join and demmand increases. Wonder what else they are skimping on.

And the more we use their services the more we pay them. The more we use it the more it costs them. As we use it they make profit because we pay MORE than it costs them to SUPPLY their service to us. So the more we use it, the more we pay them, the more they profit, the more infastructure is needed to supply us.

How hard is it to keep up with demmand when we use more.
