Hi,

I came across your website while browsing Google and noticed there may be an
opportunity to improve your search visibility with a few relevant, high-DA
backlinks.  Sometimes small changes in off-page SEO can make a big difference in
rankings and traffic.

I identified a couple of backlink opportunities related to your site so you can
see what stronger off-page SEO could look like.

You can review them here:

Information about the closure of Myrient

Hello everyone,

I have decided to shut down Myrient on 31 March 2026.  Until then, the site will
continue to remain available in its current state.  Please download any content
you find important, as you have around one month to do so.

There are several reasons for the closure:
- Insufficient funding
As traffic continued to increase last year, the amount of funding from donations
remained the same.  I have been paying more than $6000 out of pocket every month
in order to cover the difference which is not sustainable.

- Paywalled download managers
In the past several months, many specialized download managers were created that
completely bypassed the site, donation messages, and download protections.  Some
of these download managers locked certain features behind a paywall that required
users to pay in order to gain access.  The use of Myrient for commercial,
for-profit purposes has always been strictly forbidden.  Such egregious and
abusive usage of the site cannot be tolerated anymore.

- Rising RAM, SSD, and HDD prices
Since last September, RAM, SSD, and HDD prices have surged dramatically and
continue to rise due to the ongoing extreme demand for AI datacenters.  This has
caused Myrient's hosting expenses to go up as well.  Necessary upgrades to the
storage and caching infrastructure only exacerbated the problem.  With a large
number of servers and the aforementioned existing monthly deficit in excess of
$6000 out of pocket, there is no way to pay for the increased hosting and hardware
upgrade costs.

There are still many other smaller reasons, I could go on and on about them, but
nobody would want to read it.

In short, I can no longer afford to run the site.

If you have any comments, you can send them to support@erista.me (I will read all
of them and might respond to a few).

Thanks for using Myrient over the years.
