The statement is directly confirmed and corroborated by multiple sources. Source 1 (BeInCrypto) explicitly reports in its headline and content that Coinglass was affected by a large proxy attack which disrupted access. Source 2 (CoinGecko) directly corroborates this information by citing the BeInCrypto story with the headline 'CoinGlass Hit by Large-Scale Proxy Attack – Access Disrupted'. The other sources are irrelevant as they do not address this specific incident.
