action=ulslocalization is the most common API request on the cluster at the moment, amounting to ~41% of all requests. You shouldn't call the API on every page load. Find an alternative to using the API and/or don't load the language localization data until a user clicks on the cog icon.
Please get in touch with Greg G. to schedule a deployment for a fix -- this should be done ASAP.
