No. However, installing an IRC client is allowed.
At Easyspeedy we host a lot of commercial sites and applications belonging to companies, societies,
associations,
and individuals all over the world. Part of, or all of their business is based upon availability from the
Internet
and of their server(s).
By nature such applications are extremely
vulnerable to e.g. DDOS (flooded pipes), and represent from a security point of view, a
hazard on any network. Any irregularities that will incur a risk of harming our customers
is therefore not allowed.
A short visit at CERT Coordination Center http://www.cert.org/, and a
search for for instance 'irc' will reveal a long and sad track-record of vulnerabilities.
