WARNING: The DNS entry for "phial.com" was wrong for a year and nobody noticed. The Puerto Rico server has been down since 2012, because the Curl RTE (still) does not support 64-bit linux, and I have been too busy to convert it to Python. In fact, pretty much nothing on this site has been updated since 2012.
You are probably looking for the Puerto Rico Online web page.
You might be looking for the old Official Angband Home Page.
