Date Time Explanation
09Aug09 16:25->18:05 There has been an unscheduled outage at 55 King St (iPrimus data centre) caused by equipment failure which impacted all our name lookup servers during the period shown. Issue is resolved.
27Jun09 21:15->23:30 There has been an unscheduled outage in the PowerTel network caused by equipment failure which impacted all our data feeds during the period shown. Issue is resolved.
06Aug07 07:30->08:15 There has been an unscheduled power outage at Global Centre in South Melbourne which impacted both our data feeds during the period shown. Issue is resolved.
23Jan07 10:30->30Jan07 10:00 aDSL service provider Comindico/SPTel has an issue with the main router in Melbourne causing users to be knocked offline and not being able to reconnect for a variable amount of time. It has been determined that the fault lies in the hardware and a replacement is being installed. Update: 30Jan2007 10:00am - Issue is resolved
15Nov06 16:00->16Nov06 11:30 aDSL service provider Comindico has introduced a new range of IP addresses which are allocated to end users. This new range has a routing issue which is preventing browsing to some sites (including ANZ, NAB, bureau of meteorology, techinfo, Bank of Queensland and others). 11:30am - Issue is resolved.
A routing issue at Prodigy (upstream) has caused slow browsing
performance in the period shown.
A power loss to the Briar Hill area has resulted in system shutdown
(only) during the period shown.
18Dec05 14:30->14:40 A short loss of external connectivity as we swapped core router to new unit as preparation for increased bandwidth.
03Sep05 11:10->19:00 An intermittent issue with the core router resulted in variable connectivity throughout the day as we have chased the problem. We believe it is now resolved and all services have returned to normal.
16Jul05 10:10->11:15 A hacker ran a 'ping flood' on the proxy machine rendering all external access to the net useless.
15Jul05 10:35->10:55 We have implemented a second fail over link to both increase bandwidth and provide some redundancy. The live test did not work and a routing loop resulted in no external connection for the period shown.
01Jul05 14:30->16:30 A Telstra data line fault has removed all external access to our servers. A temporary solution to restore connectivity is now in place until their technician arrives to replace the faulty equipment and restore the service.
27Apr05 20:30->28Apr05 10:00 Change to Telstra services knocked out all 56k indial lines between the period shown. All issues are fully resolved.
09Jan05 03:00->09:30 Browsing performance very slow due to a proxy server software issue - issue fully resolved, services returned to normal.
06Jan05 12:30->12:45 A short interruption to services whilst the main router at AAPT was replaced with a faster unit.

23Nov04 03:00->17:15 A customer's web page hosted on our server caused tremendous outgoing load resulting in a "Denial of Service" attack - all browsing slow during the period shown. Issue fully resolved.
14Oct04 21:15 Routing issue resolved on new router which has improved access speed.
07Oct04 07:30 New (more powerful) router installed in core network in preparation for bandwidth upgrade. Second machine to be installed at network border in next few weeks.
29Aug04 00:15->09:15 Main web server off line during the night whilst some upgrade work was performed.
16Aug04 18:30->17Aug04 10:30 There was a routing issue with one of our upstream providers during the period shown which prevented access to secure sites (banks, etc) and some other international sites. This issue has been resolved.
02Nov03 12:30->14:00 We restarted the proxy server several times in the period shown to implement a solution to the proxy server issue below. This problem should no longer be an issue with the network.
28Oct03 21:30->23:45 A problem with the proxy server software stopped browsing outside the network during the period shown.
27Oct03 16:00 A problem with duplicate IP addresses on an access server which was swapped in to the network as a replacement for a faulted unit led to 'dead' connections for some dial up customers - this has been resolved.
27Oct03 12:00 A problem with the 'online time usage web page' is being resolved - users cannot check their usage on line at this time.
There was a short duration outage of the RADIUS (login authentication
system) server whilst we tested some changes to be made during the transfer
the the new higher speed web server over the next few weeks.
13Oct03 15:00 Have just commissioned a new more powerful proxy server replacing the previous unit. There was a five minute shutdown whilst the changeover occurred.
10Oct03 12:30->04:00 The performance of the web server was down as Chinese based spammers sent tens of thousands of mail messages to third parties. They and others have been blocked from doing so again.
06Oct03 11:30->07Oct03 09:05 All mail external to the techinfo network was rejected during the period shown as a black list we use to check for spam sources was faulting to reject all incoming mail. We no longer refer queries to this list.
06Oct03 11:30->11:35 All modems were shut down to allow installation of additional UPS and battery capacity. Several machine restarts were executed during the day as mail server and proxy server changes were updated.
29Sep03 18:30->18:40 The network was isolated from the internet as we replaced the gateway router with a new unit with more RAM installed to improve network performance.
22Sep03 17:30->18:30 The mail server machine was swapped for a complete new server today during the period shown. The service was stopped/started many times during the window causing some issues with mail delivery. All services returned to normal at the end of the period shown.

Power restored at 02:07 and system restarted with a proxy server fault which was corrected and network became fully operational at 3:15am - network totally offline from 01:43am ->03:15am. All incoming mail will arrive.
21Feb03 11:32->12:45 Total power failure in Briar Hill area during the period shown. Whole network running on UPS battery for the duration. All services continued to function on battery power and no services were interrupted or impacted by the outage.

Whole network running on UPS battery for the duration with supplemental power being supplied by long lead to an adjacent premises. All services continued to function on battery power and no services were interrupted or impacted by the outage.
24/25Jan03 22:30-07:30 A software problem with the proxy server stopped all browsing traffic and external access through the night. Problem has been solved and all services returned to normal.
24Oct02 16:30 We have changed the filtering software to another system and should be as aggressive in removing spam and less trouble to maintain.
04Oct02 18:00 We have implemented much more agressive spam and virus filtering software which analyses every incoming and outgoing mail message for typical spam content and virus attachments. These are deleted from the data stream. All users should receive very few spam messages as at this time.
18Sep02 17:40->20:39 Power failure in Briar Hill area during the period shown. Whole network running on UPS battery for the duration with supplemental power being supplied by very, very long lead to an adjacent premises.This is the longest power outage ever experienced. All services continued to function on battery power and no services were interrupted or impacted by the outage.

machine shut down once again and would not accept calls.
05May02 19:32->21:35 One 56k access machine
