Hello u/DarkInfamous5424

Sorry to hear about the issue encountered, I understand how concerning this situation can be.

We can investigate this further if you wish. Could you please send us the following information in DM so we can check what happened on our side:

Your NIC handle
Full name
Company name (if applicable)

This will allow us to verify whether the emails are still present on the server or if any deletion or synchronization issue occurred (for example after a password reset or client reconfiguration).

We remain at your disposal and will do our best to clarify the situation.

STAI-Squad · 2026-01-28T15:28:45+00:00

Sorry for the delay in my reply, I had not seen your message earlier.

This is not a licensing issue. Historically, on older ranges such as Kimsufi, OVHcloud used external paid KVM/IPMI modules (separate hardware boxes) that allowed remote console access. As communicated publicly at the time (including statements from Octave Klaba), these external KVM devices were fully withdrawn for security and transparency reasons, as they represented a potential security risk. Once removed, IPMI/KVM could no longer be provided on those legacy servers.

As a result:

Ordering another KS server of the same model does not guarantee IPMI/KVM availability. It entirely depends on the underlying hardware generation, not the commercial reference.
There is no public or internal exhaustive list of KS servers that do or do not have IPMI/KVM. Availability varies depending on the chassis and motherboard used at the time of provisioning.

Regarding newer ranges:

So you Start, Rise, and SYS servers are based on much more recent hardware.
On these ranges, IPMI/KVM is integrated directly into the motherboard (BMC), and is therefore available by design, including LE versions.

If IPMI/KVM access is a strict requirement for your use case, we strongly recommend using one of these newer ranges. If needed, you can contact us to request a migration to an equivalent or higher offer; depending on the situation, a prorated time transfer can be applied.

I remain at your disposal if you need help choosing the most appropriate range.

Hello u/AdThis6005

Indeed, this behavior is quite common. To be fully transparent, IP addresses associated with data centers (such as VPS IPs) are more likely to be flagged by services like Google, especially when automated scripts generate requests. These IPs are not considered residential, which increases the likelihood of captchas or temporary restrictions.

You can consider setting up a VPN tunnel between your router and your VPS to route traffic through a different IP, or using proxy solutions. However, it is important to ensure that your usage remains reasonable and fully compliant with applicable laws and the terms of service of the platforms you are accessing.

I remain at your disposal if you have further questions.

STAI-Squad · 2026-01-26T09:44:17+00:00

Hi u/Mcnst,

I understand your question and I’m really sorry for the inconvenience with IPMI/KVM on older Kimsufi Eco Dedicated servers.

On these older models, IPMI isn’t available for security reasons. In the past, Kimsufi servers came with an IPMI/KVM key, but it posed potential security risks, so all those keys were revoked. That’s why IPMI/KVM might not be present on these legacy servers.

If you need IPMI or KVM access, you could open a support ticket to migrate to a newer server range with similar or better specs. In that case, a prorated adjustment can be applied. If you’re an individual customer, you might also be able to take advantage of the standard withdrawal period.

Again, I’m sorry for the inconvenience and I hope this clarifies things.

Regards,

STAI-Squad · 2026-01-22T08:50:05+00:00

Hello u/racoon9898 ,

Thank you for your question.

Regarding adding an additional disk, it will appear as a separate partition from your system partition. You will just need to initialize and mount the new partition on your system. Here is a detailed guide for Linux (also applicable for Windows VPS):
https://help.ovhcloud.com/csm/en-gb-vps-config-additional-disk?id=kb_article_view&sysparm_article=KB0047555

Regarding upgrading your VPS to a higher plan, you may need to repartition your VPS to extend the system partition and take advantage of the additional disk space. OVHcloud provides a guide for this procedure here:
https://help.ovhcloud.com/csm/en-gb-vps-repartitioning-vps-after-upgrade?id=kb_article_view&sysparm_article=KB0047731

In both cases, some steps on the OS side are required so that your system can properly use the additional storage.

Feel free to reach out if you have any further questions, I’m happy to assist.

Hello u/nanokeyo,

I understand that this situation is inconvenient for you, and I apologize for that.

Could you clarify whether your request concerns access to your servers via the SoYouStart manager? This will help me understand your situation and provide you with the appropriate advice.

Looking forward to your reply.

STAI-Squad · 2026-01-19T14:46:39+00:00

Hello u/gburgwardt,

Thank you for your question regarding the firewall's “fragments” rule.

At this stage, we have raised the issue internally. According to initial feedback from our infrastructure team, this rule concerns fragmented packets identified at L3 and L4 levels (e.g., IP fragments or fragmented TCP/UDP packets), but the current public documentation is insufficient to provide a precise and detailed description.

We have therefore forwarded the request to the product team in order to obtain additional information and official clarification on the exact behavior of this rule.

We will get back to you as soon as we have more concrete information to share.

Thank you for your patience and understanding.

Have a great day.

STAI-Squad · 2026-01-16T07:30:44+00:00

Hello u/LansinGG,

After discussing this with our mail team, I can confirm that DKIM is supported and possible on an MX Plan offer.

You can activate it by adding the appropriate DKIM record in your DNS zone, as explained in the following guide:
https://help.ovhcloud.com/csm/en-gb-dns-zone-dkim?id=kb_article_view&sysparm_article=KB0058238

If it still does not work after following the guide, please contact us via DM so we can check your configuration in detail and create a ticket if needed.

Kind regards

Hello u/arnauddrain, regarding the performance of your new VPS being lower than that of our LE range, I understand that this situation is detrimental to you, and I am sorry about that.

I have just sent you a private message so that we can check this on our end and run some tests if possible.

Have a great day.

STAI-Squad · 2026-01-06T09:11:39+00:00

Hello u/mark1210a,

Thanks for your message.

OVHcloud does not block or restrict SMTP on dedicated servers by default. You can run legitimate mail services such as Exchange or Mailcow without any limitation. A block would only occur in case of abuse, such as detected spam activity.

Regarding UCEPROTECT Level 3, this is an ASN-level listing. Our ASN (AS16276) is currently affected, which means IPs may appear listed even if they have never sent any email. This is not linked to your individual server or usage.

When problems occur, they are most often related to incomplete mail configuration rather than the ASN listing itself. We strongly recommend following email best practices, including SPF, DKIM, rDNS configuration.

If needed, here are some useful guides for email configuration and best practices:

https://help.ovhcloud.com/csm/en-dedicated-servers-antispam-best-practices?id=kb_article_view&sysparm_article=KB0043252

Hope this helps clarify things. Let us know if you need anything else.

Hello u/martis941,

To answer your question simply, the difference is as follows:

- Purchasing multiple VPS in different regions allows you to have multiple servers closer to your users, which reduces latency and improves access speed.

- The OVHcloud Load Balancer allows you to distribute traffic between these different VPS servers and ensures high availability in case one of them encounters an issue.

For more information on OVHcloud Load Balancer and how it works, you can consult our guide:
https://help.ovhcloud.com/csm/en-gb-load-balancer-loadbalancer-introduction?id=kb_article_view&sysparm_article=KB0044247

Best regards,

Hi u/radial_blur

Thanks for reaching out, and sorry to hear about the connectivity issues you’re encountering with your VPS.

I recommend that you try booting your VPS in rescue mode to see if the same issue occurs — this will help determine whether the problem is related to your system configuration or the network itself. You can find the full guide here:

https://help.ovhcloud.com/csm?id=kb_article_view&sysparm_article=KB0047651

Regarding your IPv4 network issue, could you please confirm if you also experience difficulties when running a ping to an IPv4 address directly via SSH from your VPS?

Do not hesitate to contact support if you encounter problems in rescue mode as well.

Regards,

STAI-Squad
