According to the <a href="http://bg.he.net" rel="noreferrer" target="_blank">bg.he.net</a> link<br>
AS18894 has not been visible in the global routing table since November 28, 2020<br>
The information displayed is from that time.<br>
<br>
<br>
Are they causing you or someone issues Eric? Maybe they went out of business? Many businesses don’t worry about peering db entries. Looks like the website has been under constructions since 2020.<br>
<br>
Sounds to me like they made a splash, and faltered. <br>
