ATC suddenly came on the radio and, in a very raised voice said "xxx, you need to fly 280 knots NOW!"
Controllers are not the Administrator. The 250kts below 10,000' was instituted during the horizon of jet aircraft. It's foundation was to allow aircraft to see and avoid below 10000' with the mix of slow prop aircraft and fast jet aircraft. The only legitimate way to exceed the regulation is to have a signed letter from the Administrator or an Emergency.

14 CFR Part 91
[Docket No. 24456; Amendment No. 91-233]
Airspace Reclassification
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule; correcting amendment.
SUMMARY:
This action corrects the Airspace Reclassification Final Rule effective September 16, 1993. The Airspace Reclassification Rule inadvertently assigned the authority to air traffic controllers to allow aircraft operators to deviate from the maximum airspeed restriction below 10,000 feet. The authority to approve deviation from the speed limits contained in the Federal Aviation Regulations (FAR) rests with the Administrator, and the FAA did not intend to amend the approving authority. This action reestablishes the Administrator as the proper authority to permit waivers of aircraft speed. This action also corrects the inadvertent inclusion of Class B airspace in the maximum airspeed restriction effected by the Airspace Reclassification Final Rule.
SUPPLEMENTARY INFORMATION:
Background
On October 18, 1989, the FAA published a Notice of Proposed Rulemaking on Airspace Reclassification (54 FR 42916) which proposed, among other things, that the nomenclature of various airspace areas be renamed to conform with agreements with the International Civil Aviation Organization. On December 17, 1991, the FAA published a final rule on Airspace Reclassification (56 FR 65638) which becomes effective on September 16, 1993. Section 91.117 of the Federal Aviation Regulations (FAR) (14 CFR 91.117) was amended as part of this process.
Section 91.117(a) requires that any aircraft operated below 10,000 feet be flown no faster than 250 knots (288 m.p.h.) unless otherwise authorized by the Administrator of the FAA. Section 91.117(b) provides that, unless authorized or required by ATC, no person may operate an aircraft within an airport traffic area faster than 200 knots (230 m.p.h.), except for operations within a terminal control area. The preamble to the proposed airspace reclassification rule included a discussion of several recommendations received from the National Airspace Review (NAR) task group. NAR 1-2.1.3 recommended several changes to operating requirements in Terminal Control Areas (Class B airspace). Included in NAR 1-2.1.3 was a recommendation to delegate the authority to approve deviation from the 250 knot speed restriction in Class B airspace to air traffic control. The FAA had adopted other portions of NAR 1-2.2.3 through separate actions, but had not intended to incorporate the recommended delegation of authority or include Class B airspace in the 200 knot rule. However, the rule language amending Sec. 91.117(a) inadvertently included such redelegation, and that amending Sec. 91.117(b) inadvertently included the Class B airspace area. This action establishes the Administrator as the sole approving authority for deviations from the aircraft speed restrictions contained in Sec. 91.117(a) and excludes the Class B airspace area from the speed restrictions contained in Sec. 91.117(b).
Agree, controllers can't legally authorize you to go above 250 KTS below 10, and large aircraft that must exceed the limit have always had permission, controller authorization not required.
Sure just make sure you follow up with a NASA from...While an individual controller is not the Administrator, and authority to routinely operate above 250KTS below 10,000' comes by letter of agreement, if a controller says, "you need to be doing 280KTS NOW' I'm going to comply and sort of the details later.
