On April 16, CEX.IO on its official twitter account (https://twitter.com/cex_io) made an announcement: "CEX.IO ‏@cex_io  21h

Soon after the announcement, the linked article was removed from CEX.IO blog site, and the monthly maintenance cost per GHS is still $0.30 on the fee calculation page (https://cex.io/maintenance). Ironically total maintenance fee percentage went from 19% to 26% on the same day. Would someone with CEX.IO please explain what is going on here?
