GCHQ, meanwhile, is not restricted from storing or querying such a database should they obtain a copy. Further, the NSA is not barred from asking GCHQ to return queries against the content of databases they hold. Lastly, GCHQ would be wise to automate the servicing of such requests, as a cost saving measure.<p>So this restriction has the potential of slowing the NSA's phone record snooping by roughly one RTT across the Atlantic. A delay that could amount to as much as 0.15 seconds.
