The hosting service that runs the
www.chihuahuapuzzle.com site has announced that the site will be offline for maintenance for a while on 8/9 February.
The lexigame.com site will be unaffected, so I recommend everyone use that site during the maintenance period.
The service interruption is scheduled to begin some time after 10.30pm on 8 February PST (North America) and finish after 4 hours. Past experience tells me these exercises can sometimes go longer than planned. The scheduled start time is 6.30 am on 9 February UTC/GMT. Or in terms we can all relate to - 6 and a half hours after the start of the 9 February Standard puzzle.
