hi @flyingpigbaby and all,
The island 7142-4719-9129 has failed matchmaking 15:00 GMT and loaded 17:46 must be transient
Look at the fact that the next update has been loaded and so the network is being tested/stressed by all the devices that need update.
This is one of those “invisible” update, but just check an android phone and you will see this is big 3.7GB.
Looks to me like the European servers are slower and that because in Europe the children’s summer holidays starting all over Europe, it can be 46 Degrees C, !20 deg F (usa) They will play even more 
Sadly it seems if BR is slow perhaps they take resources from Creative Islands.
How comes another 3 v 3 island fails, but a 5 V 5 island will load and run? no one has an answer for that!
