At least it isn't just me who thinks its a DNS issue now

Woah that is definitely a detailed answer, thank you for that.

 

At least it isn't just me who thinks its a DNS issue now, I can't think of any other traffic these devices use when coming onto the network that could swarm it apart from the mentioned Apple Traffic, theres also a bit of snapchat which is blocked etc.

 

I Am not sure if I mentioned Fing but when I Run a scan I get a DNS warning so it again just adds to the likelihood it being a DNS issue.

I Apologise I don't have access to the network I am sure if I did I could get more details for you guys, but then again id probably be able to fix the issue myself.

 

I Will keep this answer in the event they are willing to fix it as theres a lot of domains there, I guess all have different functions but still all crucial to the running of IOS.

 

Thanks so much!
