We received the following message from our system provider Revolutionise:
"We want to make you aware that on Saturday 26 & Sunday 27 June 2021, there will be scheduled down time for approximately 4 hours.
This will be between the hours of 9PM - 1AM Sydney time (AEST)"
So this would mean between 14:00 and 18:00 Luxembourg time on Saturday 26
Thank you for your understanding
