The XMR fork took place at 07.24 am (UTC). The first XMO blocks were successfully found right after the fork as expected. Due to some technical issues, XMR blocks started to appear only an hour later. The network was divided between the two coins as follows: 30% of hash power went to XMR, 70% to XMO. The data was received at 9:30 am (UTC).
An update on XMO fork coming soon.
