I check my connection. 4 bars. and I have frickin extreme block lag. seriously, I have to break a block 4 or 5 times just to destroy it! WHY?!
The server probably has a lot of people on, try closing minecraft anf restarting it. If that doesn't work, try something else, and play again later.
Jerry and Harry already know this because EVERYONE complains about it... they're doing their best to fix it :D
Hey Guys! I have done some research and the lag is mainly caused because of 3 reasons :D The Location You Are In (Your Internet Connection.): If you live in Australia, you might have not the best internet. However, if you live in New York City, you probably have outstanding connection. Internet connection allows you to receive and send data over the World Wide Web. If you have a slow wireless internet/ethernet connection, the server data will not be sent to your laptop fast enough and even if you have fantastic internet connection, sometimes the data sent gets lost through all the other data being sent through the server. That is most likely what causes The Block Lag. How Many People Are On The Server: Sometimes when the traffic on the proxy (The Server) is high, lag will be generated because each individual person, when moving or activating their character, uses a section of the RAM used to run the server. If the RAM isn't a large amount of GB's, then the server lags a lot. If many GB's are used on the server, lag will be a thing in the past. The Type Of Computer You Have: I recommend using an Alienware laptop or desktop with an intel processor and video card. I own a MacBook Air 11'' with 4GB of Ram and 60GB of Storage. I can play Minecraft while using Skype on my mac fine with no lag but sometimes you have to check the amount of ram your computer runs on and what company made the software your computer runs on.
It's the host's connection. The IJAH staff team are aware of it. They said that it will get fixed soon.
Block lag is never from connection to the server or computer speed. A large amount of players/ not enough RAM is the reason. When there are a large amount of entities on the server or something else using a lot of the server power, the tick rate will slow down which means everything happens in slow motion basically. You will be sent backwards every 5 seconds, blocks will reappear etc.
