The daylight savings start date changed this year for Australian states. We have many servers based in Australia, and we have found that maintenance is 1 hour late to start. This is causing all our servers to alert.
Our IPM8.5 server is based on the US east coast, and it did not recognize changes to DST even though we patched the server.
I have been working with the Solarwinds support team on this issue and it has been found to be a bug. It will be addressed in the next service pack for 9.x. Unfortunately, it appears that no more patches/service packs will be released for 8.x, which means, 8.x is not actually supported. This is very disapointing for us.
