If DNS returns TempFail, this does NOT mean it runs "improperly".
In most cases it means only that queries from this DNS were unreplied,
and there are lot of reasons for this: network connectivity problems,
link load, misconfiguration of sender's DNS and so on.
As for 'include' statements in SPF records, they have no direct relation
to DNS temporary failures, but each 'include' increases number of queries
and hereby increases the probability of TempFail.
