Strange ping peaks

I usually play a lot of Battleground games, around Wednesday, the ping started to increase drastically for no reason, until now this is happening, I went to check if it was my internet provider but other things worked normally, only ROBLOX had this increase of ping, even though I'm BR, I played these games normally on foreign servers, but suddenly it started to give these Ping spikes in these specific games, I've already tried reducing the graphics, putting the network in open NAT, changing the DNS address , active DSCP and WMM marking, but Ping starts working again specifically at 11 pm (Brasília time) only on ROBLOX, I wanted to know if there is an error on the ROBLOX servers or something different (note: I play on the XBOX Series S ).
