[PUN2] Best Region: investigation and improvements
Comments
-
If you set the PunLogging to "Informational", you get a summary of the logs to the console.
I can't reproduce a high ping to EU. Got 16ms (from a regular landline with powerline adapter).

Hi, just curious is this thing still under investigation and development? Recently I've been experiencing some issue and received some bug report from players where they automatically connected to east Russian server while the closest region is Asia

It's not always geographically the closest. VPNs may skew the results. In WebGL, pings have a high fluctuation in either case and results may vary.
We can still have a look into this. To do anything but repeat myself, I would require some info-level logs with the ping results and the location of the player.

Hi, I run the test twice and got some info-levels logs for you. I'm living in Malaysia which geographically closer to the Asia server that hosted in Singapore, but it seem like the RUE server always return with the lowest ping

Those lists are very clear, even if the result is surprising: Your ping to RUE is awesome and hard to beat.
What happens when you check the ping in-game using
GetPing()?0 -
quite bad actually, around 300+- ping, but the ping is fine when I still in master server and then it go to 300+- when in the game server

Please mail us. Include the post (copy paste please) and add your appid.
Will discuss with my colleagues if anyone has an idea how this could happen.

ok done

It turns out we recently had to use a Master Server from Singapore for the RUE region. Meaning: Your ping for the Master Server was to a Singapore server but this was handling servers in Russia (which gave you the bad ping in the end).
This is resolved from our end and you don't have to update anything.
Clients will detect that their ping to RUE is no much worse than earlier and should re-ping all regions, this time ending up in Asia (with overwhelming accuracy).

Is there even a way to have PUN get what it thinks is best region without having to connect to the master server? This seems like a missing feature.

Thanks for the logs. In both cases, the clients already knew a best region and only pinged that one. It wasn't (much) worse than earlier, so the clients kept using these regions.
You can set a Development Region to avoid most region issues during development time or you could set a fixed region.
To get more info about what results each region gets you, it makes sense to delete the current "best region", which is stored in the player preferences (
PhotonNetwork.BestRegionSummaryInPreferences = null). Then, we get ping results for all regions.Setting a Region Whitelist will also make clients re-ping all (then) available regions (it invalidates existing stored results)...
