You may have found that INA is currently redirecting to Google.
This is related to a recent update, if you are attempting to access the site from IE9 or earlier it will redirect to Google.The redirect should be bringing you to an earlier version of the archives before the update and this will be implemented by close of business today.
The new updated site is compatible with Google Chrome, Firefox, Safari and IE10 or later. Therefore you should be able to access the site from any of these browsers right now.
Please accept our apologies for any inconvenience this has caused.
