Description

Due to a network maintenance on which the entire row A will be affected (T286032), we need to temporarily failover misc services to hosts outside of row A.
We can use db1124 and db1125 (testing hosts) and place them temporarily as m1 and m2 masters.

  • db1125 to replace db1159
  • db1124 to replace db1107
