One of the reason for a client leaving a hosting company is poor Server Performance. A badly performing server will be spoiling your's/your clients reputation and it might cost you in lossing clients hosted in that server. To avoid that, we checks all our servers monthly to ensure that server is performing well. If we found any issues we will fix it. Fixing may include mysql database optimization, account migration, service tweaking/fine tuning. A detailed report will be sent after verification.
