Welcome to the widest subdomain on the Internet.

ဪ is the widest character allowed in internationalized domain names. A string of 57 ဪs translates to Punycode "xn--ujdaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" - a total of 63 characters - which is the longest allowed in a domain segment. Domains are effectively limited to 253 visible characters, so this domain is of length 58 + 1 + 63 + 1 + 63 + 1 + 63 + 1 + 2. .sh is the widest 2-character TLD that supports IDN and is easily registerable, which allows for extra ဪs in the subdomain.
