co-location
collocation
<networking> /koh'loh-kay`sh*n/ or /koh`loh-kay'sh*n/ (Or
"colocation") Providing network connections such as {Internet}
{leased lines} to several {servers} housed together in a
{server room}. This is typically provided as a commercial
service.
The hyphenated form is correct and the most common on the web,
followed by "colocation". "collocation" (/ko`loh-kay'sh*n/,
not /koh'-/), is an old word with a similar meaning. It is
common in dictionaries and follows the pattern of other
Latin-derived words like collect, college, and collate, but is
least common on the web.
The verbal form is "to colocate" or "co-locate" (commonly
/koh'loh`kayt/, also (US) /koh`loh'kayt/).
