Due to a hick-up during an update of the forum software, some posts might be lost that were written between 11:30 and 11:50 CET.
To solve the issue, the forum was (unforeseen) offline for 20 minutes, without a pre-warning.
My apologies for the inconvenience.
I only saw approximately a 5-10 min bad gateway 505.
i was baking a cake while that so i do not get this at all 
Caruful, it may get lost as well. 
i prevent from that by baking a huge lasagna also 
IT went away while I was posting something, and gave me a bad gateway. However - when it DID come back, more than 1/2 of the post was still there ready to go! I guess you could call it a “low-impact” problem…
