Vodafone-NBI: High latency every evening

I had an issue last night with Vodafone on NBI where I was getting less than 100Mbps instead of my usual 900+. Lasted from around 8pm (at least that's when I noticed it) until 11pm. Ping seemed fine just very slow speed.

@pacman114 @mossie I'm assuming its unlikely you're in close proximity to one another so was wondering if it might be Vodafones DNS servers? Are you using Vodafones hardware and/or their own DNS servers or have you configured Vodafones/Your-Own router to use custom DNS servers?

Using my own DNS. It seems to have been a one off with me last Sunday, fine since then.

This is strange. I'm with Digiweb on NBI and I've been noticing the same thing. I never paid much heed to it because it didn't affect the connection - i.e. it went from excellent to very good for a couple of hours in the evening. I decided to track it a bit more after seeing this thread, but lo and behold, it hasn't happened since. Maybe some piece of NBI kit was struggling and got upgraded.

I have an issue again tonight. Ping is fine - 9ms but download is at 15% of normal.

Occasionally but not every evening. Maybe twice in the last 10 days.

Same thing is happen to me almost every evening. Did you report to Vodafone?

It gone pure rubbish

I'd suggest logging a formal complaint here:

Make A complaint Here | Vodafone Ireland

I did it and got a generic reply but at least it's logged. Their reply contained the following:

We want to assure you that we are addressing your concerns and would like to clarify a few points regarding the situation:

1. The current issue is related to infrastructure, which means that your internet speed may fluctuate based on the usage of other connections in the same cabinet.
2. Since this does not involve the fiber optic lines or our equipment, we may not be able to escalate this for a technician visit.
3. We understand this is frustrating, and as part of our commitment to you, we can place you out of contract should you decide to switch providers, allowing you to move without any termination charges.
4. Additionally, mobile broadband remains an option if you are seeking an alternative solution for the time being.

___________

All of which are bad options. Not sure if they are admitting there is a fault and are looking into it. But as you said there is nothing wrong with the fibre connection as it is perfect during the day. Issue is with their backend at peak times. Maybe an ISP change is the only solution.

Maybe don't bother, they don't consider it an issue at their end! Reply from their complaints department:

While we understand this is a concern, it is important to note that this issue is not related to hardware or technical faults on our end. It is primarily influenced by the level of demand on the internet connections to the cabinet during peak usage times.

We have previously addressed this matter, but unfortunately, we are unable to provide a specific resolution or service level guarantee at this moment. However, we would be happy to explore alternative solutions with you. Please review the options outlined below, and let us know if any of them meet your needs. We are here to assist you further.

Thank you for your understanding.

Kind regards,

Agreed. From looking at the Sky forums they seemed to have a similar issue recently and it seems they have resolved it.

where about are people impacted ? Is it a couple of pockets like Sky had. Or more widespread?
