A good news has been received from the admin of Asian Invest Group HYIP:
"We are back online and working again. We are very sorry for this downtime happened. We will make sure this will never happen again. Thank you for waiting.The recovery of our server after a hardware failure is not completed yet and because it is taking much more time than we expected we decided to setup a new server and restore the data from backup. You should be able to login to your accounts and see all your data (SSL certificate is not installed yet, will be installed later). If your weekly earning was expected on one of the downtime days it should be already credited to your account.
Because the database was restored from backup it may not contain some recent registrations and transactions made before server crash. We will check the information manually to restore everything. If something will be missed in your account please contact the support through contact form."
