[Oman]Omantel Internet services interruption: Problem with firewall or DNS Server??

Sharply I reached office 8.00 O’clock with the long scheduled tasks like sending and checking for some important mails and to browse the  topics over the internet.. etc !!

Unfortunately My mail application saying some error..  My messengers are  waiting to login .. and finally my home page saying that there is no internet connection..

I have checked my switches, access points, and finally to my router..  there is no issues internally  or with the link to Omantel but the DNS server was showing down for sometime.. After sometime again whole PPP Server and the Default Gateway to the ISP was not responding.. finally i called up Omantel  and enquired about the issue.. they said that “ there was a technical issue and our technical team was working on that. and we don’t have any idea when it will come to online”

finally the service came to online at 12.20PM

Then I checked my whole things working fine and for the testing case I have tried with blocked sites ( obliviously www.skype.com ) also amazingly its working  and  there is no Page saying that “The site you are trying to access was blocked by Omantel”… bla bla bla

And I checked with yahoo voice chat Hey its Great the calls are going..

Is there any problem with Omantel’s  Firewall or they intentionally opened??

Any way there is no restriction for browsing right now..  we will see how long it would be like this..
