An upgrade by Twitter, widely known as Twitpocalypse, planned for Friday September 11 could cause major disruption for users.
People who use third-party applications to run Twitter could have problems if the software is not set up to recognise the 64-bit number used to identify each unique tweet
Messages send via Twitter are assigned unique ID numbers, known as integers, but the number of unique 32 bit numbers is running short.
Twitter is introducing longer 64-bit Tweet identification numbers in preparation for unique tweet IDs exceeding 4,294,967,295.
This is expected to happen tomorrow as part of the company's routine database upgrades and maintenance, according to Techcrunch.com
Applications that run Twitter but do not recognise 64-bit integers could malfunction, unless they are upgraded.
A similar upgrade completed in June caused problems for some third-party Twitter application users.
