Salesforce.com will double the number of data centres that host login pools for its CRM service in a bid to balance traffic loads and increase reliability.
The company notified administrators of the impending change on Tuesday.
It asked administrators that presently whitelist salesforce.com IP addresses to add the new address ranges, noting that users could otherwise end up unable to log on from November.
Customers that do not whitelist salesforce.com do not need to act.
The company said that some of its data centres would be given login pools for the first time.
When users try to log into salesforce.com, they are routed via a login pool, "which identifies their instance and forwards him/her to it".
"Currently, we have login pools in only two of our data centres to process customer login requests," the company said.
"After this maintenance is complete, we will have login pools in 4 of our 5 data centres.
"Users will be sent to the nearest data centre for login request processing before they are forwarded to their instance."
The company's Tokyo data centre will still not house a login pool. "At this time, we do not know when we will be adding login pools to the Tokyo data centre," the firm said.
The change means Australian logins could be closest to salesforce.com's Singapore data centre. The software-as-a-service provider still does not have an Australian data centre presence.
