wikireplicas service (labsdb1009, labsdb1010, labsdb1011) run behind a pair of proxies: dbproxy1010 and dbproxy1011.
These two proxies were scheduled to be decommissioned January 2016, as they were purchased in 2011.
Finally, we were able to purchase and provision dbproxy1018 and dbproxy1019 as replacements (T202367)
dbproxy1010 -> dbproxy1018
dbproxy1011 -> dbproxy1019
The replacement should be transparent for the users, as it is a matter of changing the DNS record to point to the new hosts and let the connections move slowly. Once the old proxies are fully empty from connections we can proceed to decommission the old ones.
