The Revenue and its supplier EDS investigated the network glitch over the weekend, after the site failed to cope with high demand for filing tax returns ahead of the 30 September deadline.
According to a Revenue spokesman, the root cause of the slow access problem was narrowed down to the ‘network look-up tables’, the communication link on SAonline between its web hosting environment and its database.
After making the necessary configuration changes to the network look up tables, it was also necessary to reboot the servers.
The spokesman said: ‘It should be stressed that at no time was the filing by internet service unavailable. Since the changes have been made customers have been able to freely access SA Online once more but we will continue to monitor the situation closely.’
The message that advised people to avoid filing returns at the busiest usage times – between 7pm and 11pm – has now been removed.
The spokesman said during the weekend over 17,000 tax returns were successfully sent over the internet ‘bringing the total so far for the year to April 2003 to just under 140000’.
