Internet Archive keeps its five-year contract to build the Library of Congress's digital web-harvest collection, after the Government Accountability Office rejected a rival's argument that the agency overpaid by more than 500 percent. In an August 24, 2026 decision made public September 4, GAO denied MirrorWeb Limited's protest of the Library's award to Internet Archive under RFP No. 030ADV26R0010, closing out a challenge that turned on both price and a failed technical test.
The Library issued the solicitation to expand its web-harvesting operation, which crawls and preserves web content for the national collection. Internet Archive, based in San Francisco, submitted a total evaluated price ranging from $5.13 million to $11.34 million and earned an "Outstanding" rating on technical approach and capabilities, with a "Good" rating on the sample web crawl subfactor. MirrorWeb, of Manchester, United Kingdom, priced its offer far lower — $1.48 million to $1.724 million — but was rated "Unacceptable" on that same subfactor and eliminated before a full price comparison could help it.
Why GAO Rejected the 558 Percent Price Argument
MirrorWeb's central claim was that the Library ignored a massive price gap between the two offers. "According to MirrorWeb, the agency unreasonably 'accepted a price premium that could be as much as . . . 558 percent higher than MirrorWeb's price,'" GAO wrote in summarizing the protest. The company argued that no technical advantage could justify paying that much more for the same category of service.
GAO did not see it that way. The decision found that the Library reasonably weighed Internet Archive's price against independent government cost estimates and market research compiled during the procurement, and that nothing in the record showed the agency treated the price as unreasonable or failed to consider it at all. Because MirrorWeb's proposal had already been found technically unacceptable on the crawl subfactor, an offeror at that rating falls out of price contention — the agency never had to weigh the two prices head-to-head. The decision digest states plainly: "Protest challenging the agency's evaluation of the protester's technical proposal and the awardee's price is denied where the evaluation was reasonable and in accordance with the terms of the solicitation."
The Crawl-Test Deficiency That Sank MirrorWeb's Bid
The price argument never got far because MirrorWeb's technical proposal had a defect GAO found dispositive on its own. The solicitation required offerors proposing more than one web-harvesting technology to repeat the 100-seed sample crawl for each distinct technology, so evaluators could judge every crawler MirrorWeb intended to use. MirrorWeb proposed two crawler technologies but, as the company conceded to GAO, split the 100-seed list between them rather than running the full 100 seeds against each one separately. GAO's decision states MirrorWeb "did not perform a 100-seed sample crawl per-technology as required in the instructions," and the Library rated the sample web crawl subfactor "Unacceptable," making the overall proposal ineligible for award regardless of price or other strengths.
MirrorWeb also argued its discussions with the Library were not meaningful because they misinformed the company about the agency's true concerns with its crawl proposal, and separately that the Library treated offerors unequally by opening a second round of discussions with Internet Archive — letting the awardee submit a further revised proposal — without the same chance for MirrorWeb. GAO rejected both arguments, finding the agency had adequately communicated the per-technology crawl deficiency during the first round, and that MirrorWeb and Internet Archive were not similarly situated: an unacceptable proposal needing major revisions was not entitled to stay in the competitive range for a further round the way Internet Archive's acceptable one was. GAO General Counsel Edda Emmanuelli Perez signed the decision with a one-line conclusion that covers both the price and technical challenges: "The protest is denied."
What the Web-Harvesting Contract Covers
The award is structured as an indefinite-delivery, indefinite-quantity contract running five ordering years, under which the Library will issue task orders for Internet Archive to crawl, capture and preserve web content for the Library's permanent digital collection. Internet Archive has run large-scale web archiving for decades through its own Wayback Machine, and the award extends that expertise to a dedicated government harvesting contract rather than the ad hoc arrangements agencies have sometimes relied on for web preservation. With the protest resolved, the Library can proceed with task orders under the IDIQ without the automatic stay a pending GAO decision otherwise triggers, and the five-year ordering period gives Internet Archive a multi-year runway to scale crawl operations against the priced range GAO upheld.
What It Means for Contractors
The decision is a reminder that a sample-work test written into a solicitation is not a formality — it is graded against its literal terms, and failing to follow the stated methodology can eliminate an otherwise competitive proposal before price is ever weighed. MirrorWeb's per-technology 100-seed requirement was specific and measurable; splitting the list between two crawlers instead of running the full test against each one, even if both crawlers worked, was enough for the agency to call it a deficiency rather than a minor deviation. Offerors proposing multiple technical approaches or tools under a solicitation should treat every enumerated test requirement as applying in full to each one, not divided across the set. GAO did not ask whether MirrorWeb's crawlers would likely have performed adequately if each had been tested against the full seed list — only whether the agency's finding that the test was incomplete matched what the solicitation required.
Contractors should also note how GAO treated the unequal-discussions dispute. MirrorWeb assumed that if a competing offeror gets a further round of discussions to revise its proposal, every offeror still in the running is entitled to the same round. GAO's answer was narrower: equal-discussions obligations run to offerors that remain in the competitive range, and a proposal that is technically unacceptable and would need major revisions to become acceptable is not entitled to stay in that range in the first place. A discussion notice flagging a specific technical gap is the one chance to fix it — not a guarantee of a later round just because a competitor gets one.
The ruling also confirms a large price differential alone does not win a protest. GAO looks at whether the agency's price evaluation was grounded in independent estimates and market research, and a protester still has to show the comparison itself was unreasonable, not just that the numbers are far apart. Because an unacceptable technical rating forecloses a price tradeoff altogether, contractors bidding on federal work with defined technical demonstrations should treat those gates as pass/fail hurdles to clear before price becomes relevant, however competitive that price might otherwise look on paper.
