System is currently unavailable

Question:

"When looking at my family tree and expanding it for a few minutes I then get a "system is currently unavailable" sign and everything goes blank. This has happened many times in the last week. Not sure if I'm doing something wrong or what?"

Answer:

A recurring error message may mean that it is time to clean the browser's hidden cache folder, ie, The underlying error may have been cleared up but the browser keeps bringing up an old error message.from its cache. See How do I delete all of the cookies and temporary files stored by my internet browser? (53752) 
If that does not resolve the issue, try using a different browser to see if the issue persists. Generally Chrome, Firefox and the totally new version of Edge should work best.
Another alternative is to use a non-caching browser session such as Chrome's Incognito mode. 

If none of those helped, you may have an issue with your internet connection. Maybe run a speed test or turn the power off and then on your modem or router to reset the connection. 
To test Internet connection speed, go to any of the following sites:
