A wierd game in aram . My whole team was afk

So i went in a game of aram and after we got the champions, I got disconnected (i got the error with unable to connect to the server retry or cancel) , I retried once didn't work and then i restarted the client. When i managed to get back in the game my whole team was disconnected and the enemy team was pushing the lane , I am not sure about their Nidalee she came back later , didn't see her when i reconnected . I wrote something in the chat and no enemy responded only after the game their brand said something.

  What should i gather from this ? I only had this happen to me 4 or 5 y ago when the server were bad and i think this may be something like the disconnect hack that we had in the past . Could somehow my allies be premades on the same internet and disconnect in the same time ?
