A bit of rants here first. So my previous vps provider decides to acting up, suspending my server for overdue payment. Except that I paid in-time. I’m not sure whether this is purely coincidence mistakes or some sort. My invoice was dated due to 6th each month. Of course, as a good service provider, they sent me reminder for the payment at the end of the month by 29th, and at the 3rd of the next month.
