File Size and Format Modalities

The following guidelines apply to any domain name administrative proceeding initiated on or after May 26, 2011, that is to be administered by the WIPO Arbitration and Mediation Center (the "Center") under the Rules for CentralNic Dispute Resolution Policy:

File Size Modalities for Email Communications

Other than by prior arrangement with the Center, the size of any one email communication (including attachments) transmitted to the Center in connection with any CentralNic Dispute Resolution proceeding shall be no larger than 10 MB (ten megabytes). When larger amounts of data need to be transmitted the files can be "split" across more than one email communication.

Size Modalities for Individual Files (e.g., email attachment)

Other than by prior arrangement with the Center, the size of any individual file (such as a document in Word, PDF or Excel format) transmitted to the Center in connection with any CentralNic Dispute Resolution proceeding shall itself be no larger than 10 MB (ten megabytes). When larger amounts of data need to be transmitted, larger files can be “split” into a number of separate files or documents each no larger than 10 MB.

Total File Size Modalities in UDRP Cases

The total size of a complaint or response (including any annexes) filed in relation to a CentralNic dispute shall not exceed 50 MB (fifty megabytes), other than in exceptional circumstances (including in the case of pleadings concerning a large number of disputed domain names) where previously arranged with the Center.
