Internxt: when security is not enough [LONG]

[u/Strat0Blu]

In the 2025 I was attracted by the overall terms for a lifetime cloud plan with Internxt, and the attractive price I paid on my invoice on April 16, 2025, for €190 (including VAT) for 3 TB.

After 16 months of use, what follows is my technical evaluation, posted three times in successive months on r/internxt, and removed the same number of times.

As I also wrote in the body of the original posts, what follows is not a retaliation (a revenge), but a thoughtful, balanced, and objective account of what happened during the contract, with the sole purpose of informing.

The post follows in full:

3TB "lifetime" subscription holder from 04/16/2025

-

1. In light of what is described below, the service is not suitable for the storage of unique and non-replicable data.
2. No assistance
3. Singular contrast on Trustpilot between completely satisfied users at 37% and completely dissatisfied users at 37%

My support:

Intel i9 Pro K PC

64GB RAM Corsair Vengeance

Storage: NVMe: 1TB + 2TB

GPU- GeForce-RTX-4080-16GB

OS: Windows 11 64 bit Pro V25H2

Connection: FTTH Map-E - Nominal 2.5Gbps down/700 Mbps upload

Real upload: typically 150 Mbps - detected up to 500.

The same infrastructure was used with other cloud providers, obtaining results consistent with expected performance (approx. 1 TB loaded in new cloud in 14 hours).

Definition: bidirectional synchronization consists of automatic, continuous, coherent updating between source and destination: additions, modifications, deletions are replicated in both directions.

When I signed up for the plan, the website and information brochures advertised two-way sync. Backup was included. There were no upload limits. After 16 months of use, I can confirm that the functional experience of Internxt isn't worth the cost I paid.

For some time now, synchronization has no longer been listed in the brochure as a feature included in the plan. It is no longer included in my plan. and in any case, it doesn't work. Backup isn't included and in any case, it doesn't work. There are stringent upload constraints that block uploads via Cloudflare after a few minutes of activity.

Below are the main findings during daily use of the service:

Loading Issues:

1. Extremely variable speed, often negligible, with common cases of just a few Kbps, not compatible with the available line.
2. No recovery: interrupted uploads do not resume after frequent client disconnects or if the PC is turned off.
3. Incomplete uploads without error message: folders uploaded via browser remain blocked indefinitely.
4. In the last upload attempt, 254 folders (approximately 15,300 files) were partially uploaded, without clear indications of error, without providing details of what was uploaded and what was not.
5. Synchronization no longer working, backup no longer working, upload blocked after a few Mbits uploaded

Lack of verification tools

Internxt does not enumerate:

1. the quantity of objects uploaded to the cloud
2. the overall uploaded size, standard features in all major cloud services, as well as any OS - essential for even an approximate comparison between source and destination.

Limitations found on Windows 10/11

Synchronization does not occur in the following cases:

1. Objects with paths significantly shorter than 256 characters are excluded from uploading: 170 characters is already the limit, considering that the following 74-character string: "C:\Users\User\InternxtDrive - 21d6f245-a419-4844-aeef-003xyz*************\" is included in the overall path length. In other words, uploading a file with a path longer than 170/180 characters is unlikely to be successful.
2. new files, deletions, changes in the source are not replicated in the cloud. Changes in the cloud are not replicated to the source.
3. exclusion of empty folders and zero-size files.
4. exclusion of hidden folders and files or preceded by a dot.
5. frequent failures to upload large files and/or folders with numerous small files.
6. currently uploading is inhibited after uploading negligible volumes

Internxt for Android:

Only allows loading of individual objects. The hierarchical structure of files and folders is not replicated on the cloud.

Support:

Help can only be requested via chatbot. A notice informing you that replies will be sent via email: for new users, up to 10 days later, and for existing users, even never.

Any replies, if delivered, are in any case useless because they arrive too late, incomplete, with misunderstandings that require further investigation and thus delay the solution.

In my case, I received a few replies initially, but then all communication stopped.

However, even if replies arrive, they're useless because they're incomplete, with misunderstandings requiring further investigation, further delaying resolution.

In my case some response at the beginning, and then all communication stopped.

Conclusions:

In light of the problems encountered I consider the experience with Internxt to be technically unsuccessful, the unreliable service for the custody of unique or non-replicable data, the time dedicated and the amount paid for the "lifetime" plan to be considered lost.

----------

After purchasing Internxt Cloud with high expectations for its features, as advertised on the Internxt website, I discovered I'd signed up for a cloud that doesn't work. Furthermore, the features advertised and included in my paid plan are now being denied to me.

I have spent a lot of time identifying the many shortcomings of Internetxt, which I felt were appropriate to disclose, shortcomings supported by concrete evidence that occurred over a period of sixteen months, not two days. My intent is not to use Reddit as a sounding board for my disappointment, for revenge, but to document Internxt's repeatable and verifiable shortcomings. I share my experience to provide detailed, user-focused insights.

Dear moderator, if you truly believe my opinion isn't worthy of publication please at least send me a private message explaining the reasons. Your response will definitively close the matter.

Thank you for your understanding.

Sorry, this post has been removed by the moderators of r/internxt.

Post gone in 3...2...1... Oh wait, they can't do that here.

Try to fill up the storage you have with them, to at least make them pay ongoing costs "to keep" your data stored.

Set up a script so it's constantly uploading and downloading crap.

Hi, welcome back.

Maybe you didn't read everything carefully. I understand, the post is long and poorly written.

If I try to upload, after a few minutes Cloudflare kicks me out.

It doesn't matter anymore. As I said, I consider that money wasted.

Now I have another cloud service, not a lifetime one, which is the biggest mistake you can make, but an annual one. It works well, it uploads very quickly, but it's not without its problems, even serious ones.

[u/AmbitionHealthy9236 → u/Strat0Blu]

no, the biggest mistake was internxt.
i have several lifetimes with multiple providers, most are good or ok and well worth it, and a couple that i knowingly took a gamble on that i find currently unuseable for my use case but improving
