480344 2006-08-24 00:42:00 As of Tuesday night / Wednesday morning, it appears as though Xtra has blocked our hosting services for their customers.

We have a hosting facility in Prague, in the Czech Republic and have about half our customers using Xtra as their ISP. Then overnight those Xtra customers could no longer use our services. The reason?

Well, after speaking with Xtra's Complex Technical Team we are now at the stage where their DNS people are "looking into it". If you do a dig on our domains at Xtra, they all come up blank - error - no result.

Try it yourself: "dig @alien.xtra.co.nz ns1.jtw.cz" or "dig @alien.xtra.co.nz ns2.jtw.cz" (our name servers). Or try our website "dig @alien.xtra.co.nz www.opmc.co.nz" and you will get the same result.

I know of no-one else who has been "removed" or blocked in this way. Xtra originally told us it might be our problem, but after seeing for example that all major ISP's DNS servers in NZ find the information without a problem, it has led me to believe - as also suggested by Xtra's CTS team this morning - that it is Xtra's fault. They cannot tell me what the problem is yet, but they have said there is absolutely no reason why this should be happening.

I am now considering this as potentially anti-competitive behaviour by Telecom, as it is affecting our customers who are on Xtra, Xtra has not fixed it and and looks as though we are providing a bad service!

Does anyone have any ideas/thoughts about this? I have had a few technies on the case, but they just come back to the same conclusion - it's a problem at Xtra's end. We've just updated the SERIAL for our DNS servers, as Xtra thinks that might help, but other than that we haven't made any changes at our end for at least a month.

Cheers

480345 2006-08-24 00:46:00 I had an exact problem with my website when I had it hosted in the USA, and was unable to acccess my website through XTRA for a week, due to problems they had with their carriers. Due to this, I moved the website to a NZ hosting company. Far less trouble. I would recommend hosting your website in NZ if it is critical for your business. rogerp (6864)
480346 2006-08-24 00:54:00 Thanks for your reply. It is actually an entire hosting facility that has been removed from the Xtra DNS system. We host a number of websites, and all of them have been knocked off the grid. Any Xtra customer can no longer user our services essentially, website or e-mail or otherwise!

No other NZ company is having these issues, just Xtra. And they are only having issues with us, no-one else by the sounds of things.

480347 2006-08-24 01:07:00 Yes same situation, it was the entire NAC datacentre in New York that was unable to be accessed by anyone who used Xtra as their ISP. They evetually received enough compliants from other clients unable to access the NAC datacentre, that eventually the issue was fixed, however they never admited to any problem, but 'they were aware of it'. You will also find that some other ISPs that xtra resell to are also affected. My website is critical for my business so I decided that the small amount I was saving on hosting it in the US, that I would get a dedicated server setup in the Maxnet datacentre in Auckland and managed by a NZ web host. So far in 2 years I have not had any similar problems. rogerp (6864)
480348 2006-08-24 01:09:00 Thanks for that - very interesting. That sounds good, but we do go through 50-100TB a month of traffic so I'm not sure whether little old NZ would be affordable for us! I might check out pricing, however. opmclimited (11037)
480349 2006-08-24 01:37:00 Probably just a routing problem rather than Xtra actively blocking you. This can be an occasional problem with servers hosted offshore. Do a tracert and see where the connection is dropped, may not be Xtra.

Czech Republic sounds like a completly unintuitive place for NZ websites to be hosted though to be honest.

Don’t you mean GB? As I have yet to seen a web host that offers TB of traffic.

Good point you have there superuser :)

480352 2006-08-24 02:04:00 opmclimited, do you know if any of the users trying to access your site have the 222.15*.***.*** ip address? As if your web host has had a DoDs attack they may have blocked the 222 ip address range. stu161204 (123)
480353 2006-08-24 02:11:00 One more thought on this:

For about a week or two Xtra users could not access www.ihug.co.nz website, but it looks like that’s now been fixed.

Also take a look at these posts:

groups.msn.com

groups.msn.com

groups.msn.com

As a few of those people are having the same problem as you.

I Hope this helps
