Our report dated April 30, 2019, on the effectiveness of InterXion Holding N.V. and subsidiaries’ internal control over financial reporting as of December 31, 2018, expresses our opinion that InterXion Holding N.V. did not maintain effective internal control over financial reporting as of December 31, 2018 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph stating that the material weakness relates to an inability to obtain evidence of the operating effectiveness of internal controls at a service provider which operates a platform for processing payments and which the Company uses to pay the majority of their operating and capital expenses.
