I'm sure someone at SolarWinds is aware of this already, but just in case...
All the links on Thwack going to the SuccessCenter are broken! I see this message.
(The last URL I tried was https://support.solarwinds.com/Success_Center/Network_Performance_Monitor_(NPM)/Knowledgebase_Articles/Volume_alert_setu… )
If I just go to https://support.solarwinds.com then I am redirected to Success Center (https://support.solarwinds.com/SuccessCenter/s/)
I can then search for the document that was listed at the end of the URL, and even usually find what I was originally looking for.
