No one regret moving to HRD not because its great, instead its the M/S sucked too bad lately. 30 minutes download evey week is a disaster for any kind of app hosting on it.
At the mean time, HRD still isn't flawless. I am still having around 1% percentage of datastore timeout from any kind of datastore accesses like a simple get_wih_id(). It is slower than M/S and cost more (the /G cost is now the same since Google raised the price for M/S too, but the slower respond still cost more on instance number) The most stinky part is how Google advertise it as a 100% up time service when it is generating more exceptions than most shared MySQL hosting outside. I know I know, its about scalability. But how many apps are having hundreds or thousands of DB access every second that can benefit from its scalability which can compensate the constant flaw?
