A brief note for that for the usual maintenance patches we install to our systems (for 3rd party supplied components, MySQL, Apache etc) throughout September.
The PIT (test) system will have its updates applied on 24th September, third Tuesday of the month, between 06:00am and 07:00am GMT.
The PRODUCTION system will have the updates applied on 26th September third Thursday of the month, between 03:00am and 04:00am GMT.
In each case, this means a short period of intermittent downtime for maybe 5 up to 30 minutes whilst systems are rebooted etc. may apply.
Apologies for any inconvenience this causes but we hope the timing of this work lessens any impacts on your operations.
