We have been experiencing Log Analytics problems almost daily for the last few weeks. Response times have always fluctuated (few ms to several secs), but lately quite often queries time out or, like right now, result in a BadRequest (query error).

Is there a persisting problem that keeps causing these issues? Can we expect things to stabilize soon?

Regards,

Robert
