A major outage earlier hit customers at Post Office branches across Britain.
People over the UK attempting to send out parcels this afternoon ran into trouble as systems crashed while they were in store.
Outage reports for the Post Office shot up shortly before 3pm, according to DownDetector's tracker.
Most of the problems were about a 'total blackout,' while others indicated there was a problem with the internet connection.
It is not yet known what caused the outage, but the Post Office told Metro that it is 'not cyber related'.
Post Office posted on X to warn people of the crash when it happened: ‘We’re aware of an outage impacting our branches. The issue is being worked on and things should be back to normal later this afternoon. Thanks for your patience.’
The company said their systems were back up and running just before 4pm.
Shortly after, a Post Office spokesperson said: ‘There was a major outage across the Post Office estate this afternoon.
‘We are pleased to announce that service has now been restored to branches.
‘We apologise for any inconvenience caused to customers and the operators of our branches.’
But some customers were left furious with the outage and took to social media to share their disappointment.
One woman said: 'Bro I walked 25mins to the post office in flip flops for them to tell me the system is down & come back tomorrow, bro can u just HAND IT TO ME.'
Another added: 'No they are not back to normal! On the strength of your post I travelled again into Macclesfield only to find the post office at WH Smith still offline - system down. So - no- your services are not back to normal - unless you consider zero service normal?'
A third wrote: 'The post office servers are down all over the UK. look at their twitter. I am unable to drop off parcels as they are CLOSED as unable to function.'

One more chimed in: 'Hello, please can I arrange for my parcel that is stuck inside the post office to be delivered to my home? Been twice to collect it now and told both times “system down” unhelpful employees and rude as always.'
It comes after a spate of high-profile cyber incidents affecting the M&S and Co-op.
M&S online orders were back in action six weeks after the cyber attack in April, which cost the company £300 million.
Co-op admitted yesterday that all 6.5million people on its membership scheme had details stolen in the hack, which left some branch shelves empty.
