Update on the disruptions affecting Lnu.se and Medarbetare
(Publicerat 260508 kl 11.55)
Since the restriction of traffic from abroad was introduced, we have implemented several technical measures to strengthen the stability of Lnu.se and Medarbetare.
On Friday, 8 May, starting in the afternoon, traffic to and from the outside world will be reopened.
The IT department will then monitor the situation and continuously follow the load. If new disruptions or overloads occur, temporary restrictions toward other countries may be reinstated to ensure stability and availability for our visitors and users.
Work on additional technical improvements and long‑term measures for managing traffic will continue in parallel.
The disruptions on Lnu.se and Staff (Medarbetare)
(Published 260507 kl 08.00)
We are currently experiencing recurring disruptions when accessing our website Lnu.se and our intranet Staff. The issues may appear as pages failing to load or error pages being displayed.
We are working together with our service provider to analyse the situation and develop a long‑term solution. This may involve both technical adjustments and changes in how traffic is managed.
As a temporary short‑term measure, we are limiting parts of the international traffic to Lnu.se and Staff starting at 14:00 today, Wednesday 6 May. The purpose is to reduce the load and ensure more stable access for the majority of our users.
For those of you located abroad If you are working from abroad, you can still access the systems by connecting through the university’s VPN service. More information about VPN for Lnu computers is available here.
Causes of the disruptions The main cause of the disruptions is a significant global increase in automated web traffic. This is a worldwide phenomenon currently affecting a large number of public authorities and companies. AI‑driven search traffic has increased globally by 30 percent in a very short time.
We believe a growing share of this traffic comes from AI‑based tools that:
This means our websites are now receiving far more requests than before, often within very short time intervals.
Our current web solution has a technical limitation in how many simultaneous requests it can handle (so‑called “rate limiting”). This limitation has not previously been an issue, but is now being reached more frequently, resulting in the disruptions users are experiencing.
Our own use of AI‑based search functionality also contributes to the increased load, although it is not the primary cause.
We are aware of the frustration and difficulties this has caused. We fully understand this and sincerely apologise for the problems that have arisen.
We are working to resolve the situation as quickly as possible and will provide continuous updates.
