On Monday the new version 2.2.0 will arrive in your WordPress dashboard. To be prepared for this I’ll switch rich-snippets.io to a new server that allows to receive more requests made from the plugin.
Some users already expected weird problems mostly the loading-wheel never stops (or never updates the snippet). This is because our (shared hosting) server seems to be too week to answer all requests properly.
Due to this update, the website rich-snippts.io will maybe not reachable by the plugin during 3am and 11 am UTC.
Thanks for your understanding.
