Last night's unsuccessful hotfix means that, after taking out the entire evening Thursday from 6pm until 11pm for Australian users, they're now taking out the entire *next* evening on Friday from 6pm until at least 9pm, meaning that most working Australian users will be able to participate little, if not at all, in the first day of Midyear Mayhem.
We're usually pretty patient with maintenance consistently being done in our absolute busiest hours, but two days in a row, during an event, for a bug that doesn't affect the playability of the game for most people? 4am EDT until 7am EDT are reasonably busy hours on EU server and it's frustrating that there's never a time picked that affects less people unless things break so suddenly that ZOS has to completely drop what they're doing.
