I am also facing this problem, I am on 2degrees in New Zealand.
This happens regularly and Blizzard never seem to advise us what the cause is, the problem just goes away.
We can provide you MTR’s up the wazoo but are they actually helping anyone get to the bottom of this?
The problem I have is that Blizzard tend to always put this down to a “common routing partner in the area” – yet I have now had this problem on two different ISP’s.
The matchmaker checks latency, and my latency on my old ISP to PSE was 150ms~. On my new ISP my latency to PSE is 350ms~.
Why does the game think that this is a good idea?
More to the point, I have constant pings running to the Overwatch servers that I connect to which give me 40-50ms latency and the pings are always consistently low. So I really can’t buy the “routing problem” statement.
This has gone on for a long time on and off now, well over a year, and as I said again we still haven’t ever had an official Blizzard response as to what causes it.
Well, the time has come for this to end, and for us to get a proper response from a proper network engineer, not a tech support MVP asking us to do some WinMTR’s which (through absolutely no fault of the MVP’s, they’re doing their job) are largely useless in the grand scheme of things.
My suspicion is that Australian hosting is expensive and Blizzard in an effort to cut costs have reduced their compute capacity in Sydney, resulting in us getting put on other regions servers during prime time because the servers in Sydney are at capacity. I doubt we’d ever receive a response on this.
Anyway, this will probably fall on deaf ears, the problem will go away for a couple of weeks, maybe even a couple of months as it has done before, but then it will be back again and we’ll be back in this exact same situation.
I’m an IT professional with ~10 years experience. If you want me to run any kind of test, I’m happy to, I just don’t want it to fall on deaf ears and go around the merry-go-round again. It’s tiring and a waste of everyone’s time.
