Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !technology@lemmy.world?dataType=Post&page=1&sort=New
while I haven’t seen any official confirmation, I believe that the instance is experiencing a number of DDoS attacks (they confirmed they had been last week). Their serves have been having constant issues and experiencing extended downtime frequently over the last two weeks.
the 18.3 upgrade should help a lot with that. best of luck to them!
