Although we endeavour to always keep our systems available, one of our suppliers has let us know that they will be carrying out some maintenance work which may impact you being able to use our platform. They have advertised the following window: Start: 2017-03-07 22:00 End: 2017-03-08 06:00 During this time you may be unable to reach the website to carry out check-in operations.  We are looking at ways this can be mitigated in our next release.
