My apologies for the short site outages being experienced since we moved to the new server. These outages are not 'errors' but rather short downtime to amend something on the server to make the site run more efficiently, or fix an issue that we have encountered.
There may be more of them over the short term as we adjust/tune the site to work better on the new server.
For example, the outage a moment ago was to fix an issue within the Ausphotography competition system. So please bear with us while we tweak and tune the new server and site software to ensure the AP experience is the best we can provide.
