Is there any chance the problem is a data replication error between the proxies? According to
this post the master database is on one of the two US servers. You could try the other four proxies. The five proxies are:
proxy01.us1.voxalot.com
proxy02.us1.voxalot.com
proxy01.eu1.voxalot.com
proxy02.eu1.voxalot.com
proxy01.au1.voxalot.com
