Managed Server/Cluster hosting recommendations?

sorry if this is considered "off-topic" but I'm desperate to find a new hosting provider that specializes in managed servers/clusters. it looks as though our current host is going under so we need to move fast. we have a pretty intricate setup that involves load balancing of both web (Apache) and database (MySQL) servers. ideally the host would also be capable of doing some development work (PHP/Perl/Ruby) - for those times when we're overwhelmed with work. we're in the upstate NY metro area, and would love to find a reliable, capable host that utilizes Telehouse's NY facility if possible. many thanks in advance, brian
