I am choosing a new place for this site. That’s means probably a few days downtime. I’ll restore this site once I find another vps. I will keep writing.
Update: my communication with the the vps provider of this blog does not work well. The provider refunded me a month’s fee for the preposterous downtime of September and ignored my request to refund a whole years fee and close my account.
Considering I have no time to migrate and configure a new vps at the moment, I’ll have to use this arrangement and bide my time for the next year to get another provider.
