  • 12 June  Power supply to Invermay is off for four hours tomorrow (Saturday 13 June) while line maintnenace is performed. IDC will remain up and running on generator backup during maintenance. Schedule for the work to be done is 10:00am to 2:00pm.
  • 4 June  A hiccup overnight affected e-mail access for some users. Remedied early this morning. Our apologies for this. 9:45 Some clients reporting issues with E-Mail. We are working to isolate the cause. 11:30 Remaining issues sorted and back to regular service.
  • 19 May  21:45 Several sites showed loss of connectivity and our monitoring was reporting multiple issues. Click here for details.
  • 28 April  An e-mail account compromised and sending spam. Team have isolated it and are working to clean up.
  • 20 April AC unit regassed and serviced. Now fully back online. We are at 100% with all AC units functioning.
  • 9 April  AC unit still playing up. Needs some parts which is a little tricky during lockdown. Overall room environment not impacted with this unit out for service.
  • 7 April  One of the AC units playing up. It has been serviced.
  • 26 March  Some connectivity interrupted due to upstream DNS issues. These have now been resolved.
  • 10 March  Annual UPS checkout. All tested through okay.
  • 9 March  After a quiet February we have an issue for some e-mail users who are reporting certiifcate errors. We are looking into this now, it looks like some further updates are to be applied. Sorted later in the day. We are reviewing events surrounding this to prevent it happening again.
  • 20 January  7:55 Multiple service events underway. We will have a full page ready when we can. It is an active situation which several staff and suppliers are managing. Click here for details.
  • 6 January  Today's lesson is how hard the wind can blow. Power supply to campus has been knocked about as a result, so IDC has been on and off generator throughout the day.
  • 31 December  Arghh! Some voice services upstream from us have flown to bits. We are awaiting complete updates but it appears something broke and engineers are going to site (a datacentre) with spares to carry out repairs.
  • 20 December  Major electrical work planned for IDC. Click here for details.
  • 8 December  National transit fibres were damaged following flooding south of Ashburton. Click here to read more.
  • 11 November  Annual backup generator check time, more involved than the monthly checks. Click here to read about what was involved.
  • 15 October Power supply to campus cut. Backup systems did their job and all operations continued without issue. Supply returned after approximately 40 minutes. Lines company later reported a fault had caused supply interruption.
  • 25 September As referred to in previous entry, we have been carrying out some firewall work at IDC. One of the firewalls is not delivering the throughput expected. We are working through this to get it to the expected performance level. As we operate dual firewalls, we can rapidly change between them as required. This frees the 'idle' one for maintenance.
  • 24 September E-Mail services were interrupted for a couple of hours. And, hands up - our fault. We applied some configuration changes which affected e-mail handling. It shouldn't have, but it did. At the same time there was a rack-roll process underway and we were switching firewalls (yes a few things going on). Initially we thought the issues were firewall related so investigated there first. Further troubleshooting isolated the issue and led back to the cause.
    Our apologies, it was one of simple human error. Once found we fixed the issue. We then contacted clients who had been in touch to see all was well.
  • 23 September Annual inspection of Server Room UPS by engineer. Clean bill of health with only routine items noted.
  • 7 September - A vulnerability was discovered within the E-Mail Server software we use. Fixes were produced and distributed. We updated our servers within an hour of the fixes being made available.
  • 3 September - We experienced excessive e-mail lately; spam. This was traced back to a mailbox being compromised. Mitigation took a couple of hours to cover all the issues that arose. We urge passwords must be strong and hard to break. 
    We have reviewed the events and are adding further alerting. We are also putting together some wider monitoring to measure e-mail traffic flow. This will be drawn upon help identify pattern changes which may signal an event developing.
  • 29 August  0830 - 1010 Call services were impacted following what appears to have been a fault upstream. Multiple providers were affected, Earthlight among them. It appears to have settled and we are monitoring. We will post further details as we get them.
    Update 9 September - An upstream  provider (two removed from us) has said they experienced significant increased volume of network traffic. They say they have implemented additional monitoring in case this kind of event occurs again.
  • 19 July  Pat on back time, with behind-the-scenes-work completed. Click here for details
  • 15 July  Brief bump upsteam from us around 0530 resulted in temporary loss of access to connectivity. It was restored 15 minutes later. A planned maintnenace is scheduled between 0500 and 0600 on Tuesday 16 July. The outage itself will be 10 - 15 minutes duration while equipment is changed over.
  • 5 July  Planned maintenance work for air conditioning in the Server Room has been completed. New units are in and running along with additional humidifier assets to control the environment.
  • 2 July  Upgrade work on air conditioning in the Server Room continues. An old unit has been retired and one of the two replacement wall units has been brought online.
  • 30 June  A handful of connections were 'wedged' (technical term) following upstream maintenance overnight. Our montoring sensed an issue. We traced the problem and remedied from there.
  • 21 June  A handful of sites dropped offline for 15 minutes 12:45 - 13:00. Root cause unknown following checking everything within our realm. We are continuing to monitor.
    Maintenance planned for Saturday evening.
  • 15 June  Power to the campus went off for a time. Backup kicked in and everything remained online and protected. Things returned to normal after approximately three hours once supply was stable.
  • 16 May Planned overnight maintenance was completed without issue. Air conditioning maintenance work is proceeding. One unit has been replaced. Work is underway to prepare for another to be retired.
  • 10 May    Reminder for network maintenance planned later this week. Some maintenance work is also planned to replace two air conditioning units in the Server Room. This will take place over the next week to ten days.
  • 9 May       Planned maintenance coming up on 15 May. Click here for details.
  • 15 April   Scheduled review of airconditioning systems. A couple of issues identified so further maintenance will be carried out, heading off problems developing.
  • 13 April  A brief power supply outage to the entire campus, lasting about 15 seconds on Saturday morning. Protection systems all worked as designed. UPS protected systems, generator kicked in and the site kept running. Once supply restored and was stable failback was carried out.
  • 9 April   Chorus are rolling out a series of updates across the network. This affects bascially all end connections. The work is being done in the early hours of the morning, any time between midnight and 06:00. You connection may go offline for up to 20 minutes while the work takes place. In most cases once the work has been done it will simply return online.
  • 5 April   Some server maintenance carried out overnight. Click here for details.
  • 26 March  Core network upgrades to be performed overnight. Click here for details.
  • 24 March  Service issues detected. Resolved in conjunction with upstream providers.  Click here for details.
  • 18 March  Scheduled maintenance planned Click here for details.
  • 14 March   An authentication issue arose for a handful of connections. Once we became aware of the issue we were able to isolate the problem and remedy. We will review the events surrounding this occuring to prevent it happening again in the future.
    Our review indentified the cause which was a badly formatted entry getting into one of the authentication areas. This effectively was a typo. Once identified the entry was corrected and all authentication returned to normal. Going forward we will continue to run checks after changes have been made to ensure system operations.
  • 11 March  An issue was detected by the UPS concerning the power supply to campus. While not a cut in power, the voltage and frequency were outside of tolerance. Accordingly the system moved off mains supply and started the generator. Changeover was automatic and staff notified as it proceeded. Zero interruption to operations. Change-back was about ten minutes later once incoming supply from the grid was deemed stable.
