Did the forums get reverted to an earlier database snapshot or something in the last 24 hours? It appeared to be down from North America and is back now with at least one thread I was active in missing and several more without the most recent replies.
(Didn’t see an appropriate misc/meta board so I figured I’d ask in General.)
Forum wasn`t available for most of the day on Sunday
Forum-Post from the morning aren’t there anymore
…not limited to forums…complete domain mikrotik.com wasn’t available for me on sunday - including DDNS / Cloud Service. I am sitting in central Europe
Yup.
Down on Sunday European time. Also wiki and other help pages were down (wiki up again, help.mikrotik still down).
And yes, looks like posts made on Sunday before the downtime (maybe even Saturday ?) have vanished.
Looks like a restore gone bad ?
Let’s hope it wasn’t a hack …
Same in North America. Condolences to the Mikrotik staff who are probably having a stressful Monday morning responding to whatever it was.
Normis wrote the following on Reddit yesterday about this issue:
Power related issues have caused a chain of events in our internal server system, we are working on it.
All services are back 
Any thought to add geo-redundancy to at least your core services like: website/download, help.mikrotik.com, and cloud.mikrotik.com?
/ip/cloud was out previously, so this isn’t the first outage. For LTE devices that roam, some DDNS is needed to located them. And, /ip/cloud is the only supported way, but it apparently is a single point of failure.
