Since early this morning I cannot access my website and also using putty I couldn't access the server. However I have other accounts on the server and I can access these websites and they are loading fine.

The OS is CentOS6.

My IP is not blocked because the server is down for all other people and I didn't change the password.

I cannot access the server using putty and FileZilla, however I could access the root using the following method:

  1. I opened a connection to another remote server using PuTTY
  2. sftp to access the server

I downloaded the error log and nothing in it. The website is using wordpress.

I did try to check the DNS and there seems to be issues which sadly I don't understand.

The webhosting doesn't support software issues and they couldn't access the server too.

I can't reproduce this. The website opens for me without problems. – etagenklo Apr 16 '13 at 11:17
thanks. I tested it on 3 servers in europe. I can see it working on sites like which gave an error all the time... really irritating not to know what is happening .-( – Momo Apr 16 '13 at 11:27
Those DNS issues you don't understand - figure them out, or seek advise. You won't get far telling anyone there are "issues" but not saying what they are. – dunxd Apr 16 '13 at 12:05

One of your authoritative name servers is not responding:

The working one:

> dig

; <<>> DiG 9.6-ESV-R4-P3 <<>>
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 51207
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
;; WARNING: recursion requested but not available

;          IN  A

;; ANSWER SECTION:       14400   IN  A

;; AUTHORITY SECTION:       86400   IN  NS       86400   IN  NS

;; ADDITIONAL SECTION:  14400   IN  A  14400   IN  A

;; Query time: 9 msec
;; WHEN: Tue Apr 16 15:16:19 2013
;; MSG SIZE  rcvd: 127

And the broken one:

> dig

; <<>> DiG 9.6-ESV-R4-P3 <<>>
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached

This will cause a random selection of roughly half your visitors to be unable to resolve the IP address for your site.

My guess is that bind is not running on your other server.

There are some other problems with your DNS. No glue for your second authoritative nameserver is a problem. You will need to go to where you registered the domain to fix this.
