Bin.sx is a very simple paste tool without unneeded functions, without downtimes, hosted in a premium cloud infrastructure for a performance never seen in any paste tool.
As you can see we are always making changes to improve the website, but the pastes are never lost, and we will do our best to keep them online, We know that advertising can be annoying, but that guarantees your pastes for years, if the page goes down, we stop making money.
You can use other similar tools that don't have ads, but they probably close very soon and you will lose all the content, they are not going to spend money to maintain the web for you.
Happy pasting.
