I wrote up the same/similar issue happening here on the east coast in America too: Rubberbanding/Lag Issue Replication & Detailed Steps
It doesn’t seem to be impacting everyone but still many people under a certain confluence of conditions. I suspect its new server config issues, routing, or volume related. All we can do is sit tight and hope they’re working on it but its been mostly silent from what I can tell. I can’t play comp because the experience swings between occasionally annoying and unplayable. Even QuickPlay is tough to get through, I tend to stick to less aim intensive heroes just to get by for now.
