Host name unavailable

Question

A week ago I changed the nameserver addresses and some other DNS records (A, MX, CNAME) while moving a website from one hosting provider to another.

Everything seemed to work out fine, but apparently the domain name / hostname does not point to anything for some individuals, even after more than 2 days.

The problem

From home I am able to reach the website without any problems from both my laptop and mobile devices. However, from work I cannot reach the website while using the same laptop I had used at home. So I thought the network had somehow cached old DNS settings, but this cannot be true, because I can still reach the website from the same network on my mobile devices.

The error at work is just oops, Google Chrome cannot find [domain].

What I have tried

I tried to flush the DNS settings at work, but that didn't fix the problem.

Furthermore I tried to ping the domain at work, but it just says

ping [domain name]
Ping request could not find host [domain name]. Please check the name and try again.

Also I checked http://www.dnsstuff.com/ if the DNS was configured well, but that gave only some warnings, no errors.

Below are the DNS settings listed

How is it possible that the hostname can not be found, depending on the network used, even though a mobile device can find the hostname on the network for which my laptop cannot? What could possibly be wrong?

Edit, nslookup -debug [domain] 8.8.8.8 gives me:

Answer 1

Your domain has a DNSSEC validation failure, as you can see on http://dnssec-debugger.verisignlabs.com/gsvnet.nl. There are no RRSIG and DNSKEY records for the domain. This is why Google DNS (and perhaps also other DNS resolvers) return a SERVFAIL for your domain.

From https://developers.google.com/speed/public-dns/faq#gdns_validation_failure:

How does Google Public DNS handle lookups which fail DNSSEC validation?

If Google Public DNS cannot validate a response (due to misconfiguration, missing or incorrect RRSIG records, etc.), it will return an error response (SERVFAIL) instead. However, if the impact is significant (e.g. a very popular domain is failing validation), we may temporarily disable validation on the zone until the problem is fixed.

You should contact your registrar/hosting company and have them disable/fix DNSSEC.
