Joke thread?
If it's for real...
From OFCOM's adjudication on the 2007 final.
Quote:
“Channel TV explained that The X Factor’s service provider, Harvest Media Group (“Harvest”) works with BT Agile Media to deliver the UK vote. This is achieved by use of BT’s Recorded Information Delivery Equipment (RIDE) platform which has a capacity to handle over 200,000 votes per minute.
In response to Ofcom’s request for information to explain why viewers were unable to get through to vote for their chosen contestant, Channel TV provided data to demonstrate that the line availability of the RIDE platform is designed to be “phone number neutral”. Therefore all callers have an equal chance of getting through, irrespective of their choice of contestant. In other words, the chances a caller has of getting through are not determined by the “voting number” (usually the last three or four digits of the telephone number), but by the number of callers overall calling the shared first digits of the voting number, therefore no individual contestant could be disadvantaged disproportionately compared to any other.
If call volumes exceed the capacity of the RIDE platform at any given time, all those calls, irrespective of the chosen contestant, fail to get through. Channel TV provided data to Ofcom that it had sourced from BT to demonstrate that there was adequate capacity on the RIDE platform to handle the large amounts of calls generated by the live final. However, it remained possible that individual network operators may have experienced problems with their own servers due to instances of high call volumes.”
