The default value for "MAX_CONNECTIONS_PER_HOUR" and related resource limits is "0".
http://dev.mysql.com/doc/refman/4.1/en/ ... urces.htmlYour webhosters are cutting down on resource consumption by imposing new limits. I would not get legal with them, but suggest that you show them evidence of the old value and mention that since you are paying them the same amount of money, were not notified of any new restrictions, no longer have a functional site, etc., they may be breaching the original agreement you have with them.
"50" is an absurdly low value. Few visit my sites, but I get many more hits than 50 per hour.
