Virgin Media appears to be down with broadband customers across Ireland and the UK struggling to get online.
The issues are affecting people in all parts of the country with complaints reported of the internet being down in the republic as well as several UK cities.
Users are reporting no broadband or a very slow internet speed.
Many are getting frustrated as they try and connect during lockdown.
Niall wrote on the Down Detector site that his connection drops 'every five minutes', Mirror.co.uk reports.
He said he keeps having 'to turn the router off and on just to get another five minutes access" adding "what a joke."
One user, Christopher OReilly tweeted: "Looks like Virgin Media just went down for the whole of UK (judging by tweets) and Ireland (judging by the laptop with lost work I just hurled across the room)."
Virgin has been responding to complaints on Twitter, saying it is investigating a 'fault'.
Its official account said: "I'm sorry that you experienced this issue, we are aware that there was a fault, and we are working hard to get this fixed ASAP."
