Cassandra timeouts 3.11.6

Hi, We have a cluster of 4 nodes all in one DC (apache cass version : 3.11.6). Things were working fine till last month when all of a sudden we started facing Operation time outs at client end intermittently. We have prometheus+grafana configured for monitoring. On checking we found the following

Hi, We have a cluster with one Data Center of 3 nodes in GCP-US(RF=3).Current apache cassandra version 3.11.6. We are planning to add one new Data Center of 3 nodes in GCP-India. At peak hours, files generation in commit logs at GCP-US side on one node is around 1 GB per minute (i.e 17+ mbps).
