Updating of the tables on frdev1001 seems to have stopped. Looks like the last entry in pgehres.bannerimpressions was around 2020-06-16 04:29:00, and in civicrm.civicrm_contribution was 2020-06-16 04:46:18. I checked in the Civi interface itself and donations are still coming in there.
There's a load of warnings in IRC
PROBLEM - check_mysql on frdev1001 is CRITICAL: Slave IO: Yes Slave SQL: No Seconds Behind Master: (null)
Going to postpone the India test because of this.
