A mistake was made by an individual from a third-party server management team who control configuration / setup of the iGP servers. They mistakenly configured it to use Daylight Savings Time rather than stick to the GMT time zone. This resulted in some races being skipped and others running an hour early.
This mistake has been rectified and we will address requests to reset / postpone races if necessary, in this thread:
