Guinness Book of Records
The Domain Name Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.co.uk was listed in the Guinness Book of Records in 2002.
At that time, the maximum number of characters allowed for an internet domain name was 58 (not including the suffix).
This limit was subsequently extended to 63, which, luckily, was exactly enough to enable the name of the upper part of the village to be registered. So an even longer domain name was registered with the 'uchaf' ending.
Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochuchaf.org.uk now holds the record as the longest valid (i.e. not made-up, such as abcdefg...etc.) domain name in the world.
The additional 'uchaf' signifies the upper part of the village. In the same way, the lower part of the village would be called Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochisaf.
