I know that the servers are located in Germany and i live in Chile so its not the best (200-400ms)
A few days ago I started a new survival with friends, the server was not going so well despite using PaperMC, optimize it with a guide and was better, however since yesterday or the day before yesterday I have had very high ping spikes (over 1000ms) and that are extremely frequent and is unplayable (finish one and start another)
I'm gonna test what happens with other servers and see if the same thing happens
