Ask HN: Do you often see issues with Datastore writes in Google App Engine?
Logs on Google App Engine show errors with this text:
Datastore writes are temporarily unavailable. Please see http://code.google.com/status/appengine for more information.
However that status page shows 100% availability and only green OK symbols: http://imgur.com/ug3JF
Latest problems were last night, writes were not working for 35 minutes.
I have seen this two or three times in the last few months, and have worked around it with additional application logic. Luckily I am not writing anything vital. But this makes me wonder: What should I do for stuff that must be written somewhere? And how can I ever be sure of the status if such events don't show up in the status-page?
Does anyone else have similar experiences?

- asmosoinio 15y agoThanks! I had not seen these resources before. On a quick glance the listed events seem to match with what I have been experiencing.
