I have a company site in Office 365 that was migrated from BPOS. Accessing the REST APIs in Chrome and in the Objective C on this site causes awful delays and time outs. At the same time, another office 365 site and my personal site under the company account both work fine. The site in question also opens reasonably quickly in Internet Explorer. Any ideas? My head is totaly destroyed by this problem. Please note, this is specific to REST APIs only! (e.g. listdata.svc or _api/web). When i navigate the site using jquery view of the default Team Site template there is no issue.
