Why I report this now:
Back in 2017 or even the following years, we were happy about the release of the Minecraft Realms on Bedrock. Slowly more and more Platforms got added. Back in the day, everybody experienced some sort of lag and no Realm was running perfectly. But it was not to bad and way better than external servers. I played on Realms with maps, that had to load a couple GB. It was fun.

The first problem:
Me and my colleagues experienced extremely annoying bugs, lags and bad Latency, after Realms moved to Microsoft Azure. You might say, it was because we did not really clear the world and explored hundred and hundred thousand of blocks – no, the lag started right at the beginning.

It was not to bad and all tough playable and enjoyable. But sadly, when we made the world a few MB big, and even more when we came close to 1 GB, especially the high Latency and therefore Lagging of Blocks while placed / broken, Lagging of Players and Mobs and missing chunk loading appeared more often and often.

The second problem:
Due to the little RAM and the interface not really being helpful, we also experienced our server to set back about 30 minutes even though the last backup was just for example 3 minutes old. This happened a lot and is annoying, each time you loose about 30 minutes of progress...

The third problem:
Then there is this thing with resource packs... I chose a resource pack and selected it on our realm, but did not forced other players to download it, kept it optional. But the pack does not appear in the "active resource pack" section and so i cannot remove it. Many players downloaded it accidentally and because they believed they could withdraw their decision – no, this does not work either.

Conclusion:
I am happy about the given opportunity and would love to pay Microsoft 8 bucks each month for running and functional servers. But in four years I never had such a bad experience and the players cannot really enjoy their time on the realm. This makes me sad.

It may be, that the latency is that high due to our location. But this should not be a problem for Microsoft...

I hope that not that much players are experiencing bad connection like we do and I hope, Realms will shine bright as a working server system for all players in the world again.
