Dear readers,
Since 25th July 2011 morning, we have been receiving feedback and reports from our readers that they were unable to access our main domain,
www.temasekreview.com with some reflecting that they were being redirected to a search engine page while some are seeing a “domain name expired” screen, other readers weren’t able to access our site at all, returning a blank page.
After consulting our hosting provider, it was revealed that our doman name did expired for a few minutes but the automatic renewal process kicked in and renewed it. However, since most Domain Name Servers (DNS) around the world have already cached the expired status, the domain name although renewed, would appear lost depending on the Time-To-Live (TTL) of the respective DNS around the world.
As of 26th July 2011 @ 1700 hours, most of Singapore’s ISP have already refreshed their DNS and is correctly resolving the domain name. However, we do have reports from SingNet users that our domain name is still inaccessible to them, which can only be attributed to a slow and unnecessary long TTL implemented on SingNet’s DNS.
Unfortunately, there is nothing we can do on our end to resolve this except to advise our readers affected to “sit it out” patiently and wait for SingNet’s DNS to refresh its cache.
Proposed Alternative
Readers with some IT knowledge can circumvent the resolving issue by changing their local DNS to the following instead of using SingNet’s slow DNS to the following:
and 8.8.4.4 or 208.67.222.222 and 208.67.220.220 or a combination of any of the 2 listed. We would recommend taking 1 from each subnet, ie: 8.8.8.8 and 208.67.222.222 for example.
Changing your local DNS to the above will not in anyway affect the performance of your local PC to resolve other domain names. It is not necessary to change it back to your local ISP’s provided DNS at all and will perform better due to the short TTL implemented by these providers.
For readers with little IT knowledge, please follow the following step-by-step instructions to change your local DNS (at your own risk) for Windows XP:
DOUBLE-CLICK on the connection icon (2 small blinking computers) located on the right-bottom of your screen on the left of the time. You should see the following screen.
SINGLE-CLICK on Properties which would bring you to the following screen.
SINGLE-CLICK on “Internet (TCP/IP)” and SINGLE-CLICK on Properties (circled in red) to open the following screen.
Click on the “Use The Following DNS” radio button and enter the DNS IP addresses provided above and leave the settings page by Confirming it all the way until you are out of the settings panel.
Normally, the Network Interface card (NIC) will reset itself and reconnect but if it doesn’t, please reboot your PC.
Should you have any further issues accessing our site after you have tried the above, please contact us with our online webform or try accessing our site through a web proxy.
We apologise for any inconvenience caused.
