Some of you will see a warning when visiting the site.
This is due to some moron at our DNS hosting company who changed a setting without knowledge nor was it requested.
Complaint made and being fixed now.
Rest assured there is zero risk in using simviation.
We are moving DNS numbers and sometimes this will cause a site to seem down or not available. Please be assured we are here and will be visible to all PC's in hours or a day at worst.
Apologies and I'll keep you updated. Please just skip the warning and use the site as normal.
