I am having the same issue in FL, blizzard said it has something to do with Verizon internet (frontier in my area). I lost 100 SR and got a temp ban on ranked. I have never once left a rank game and now my account has been flagged because of their issue. We should totally be compensated SR or some kind of league tokens/ loot boxes if they aren’t going to give us SR.
We are aware of connectivity issues affecting primarily Verizon FIOS customers in the US and Telstra customers in Australia. If you have a different internet provider, there may be some shared routing that is being affected by the same issue.
This is currently being looked into by our engineers and we will be providing updates in these threads:

*Please note that we will not be able to restore any SR or placement matches in Overwatch that may have been lost due to ISP connectivity issues.
Thank you for reporting this and for your patience while we investigate these issues, and please follow the forum threads linked above for new info.
