" Upgrading to HRD will solve your issue. M/S is deprecated and there is a clear and straightforward path to migrating to HRD."

Can anyone explain why this is not possible for them?

Wonderful Google support apart, there are a lot of alternatives out there.

"M/S is deprecated and there is a clear and straightforward path to migrating to HRD."

M/S was deprecated April 4, 2012, so it has been some time since the notice has been out there. High replication data store has been available for over 2 years now. Whether or not less than a year is too short a deprecation period is another issue.

Seems to happen on HRD as well.

Quick tip for anyone making a system with high load and daily or hourly quotas: When an account is created, assign a random start time (e.g. 05:43 for daily quotas or minute 12 for hourly) to measure that account's quotas against. Then you can avoid this issue of the system getting a huge spike in load when everyone's quota refreshes at the same time.

Multiple comments mentioned that this occurs in HRD as well.

Well, the bug report doesn't really invite quick attention. Simply reporting your observations is not enough: you should position yourself as a competent customer, by explaining what you have done to ensure the problem isn't on your side. Mention the code hasn't changed, that you have no database cleanup cronjobs or similar running that could be interfering, etc.

My first instinct when I see a report like this is: he probably has some cronjob running he forgot about; perhaps one whose performance decreased with O(n^2).

By which I'm not saying that Google is right in not replying for days, but by which I am saying that as a customer, there are easy ways to get attention beyond shouting and threatening. Show it's an interesting problem and you're bound to get some techie's attention.

I consider him panicking more than shouting and threatening. I couldn't imagine having that kind of treatment as a vps customer else I'll be moving out asap.
