Ignoring data in Piwik or web server!


In a Piwik System, in case of database crash, it may take few minutes to few hours to recover the database, in this time nobody can connect to the Piwik to save data.
We are recording data for multiple websites, is there any fast and easy way to hide the database problem from visitors of registered websites during the recovery time?
Something like a fake version of Piwik which ignores saving log data!
(Backup server / forwarding data to another server …)
Thank you
