At this stage I haven’t seen any outage advisories or news-flashes or anything to explain it, but it appears that ServerPronto (who host this server) just had a big hiccup:
Both Trouble and Zikzak went down at about 10:00am AEST and came up again briefly from 10:50 to 11:00, then went down down again until about 11:05.
Uptimes on Trouble and Zikzak at 10:50 were 3 mins and 20 mins respectively, suggesting that there had been some kind of widespread power outage at the site, but there is nothing to suggest that power was lost during the second outage.
ServerPronto’s billing website was down throughout and is still down at time of writing.
Will follow up here as any further information becomes available.
