borec se vydaval za fb employee, ucet ma na redditu jiz smazan:
It's still in the top level post but I've repeated it here for posterity...
/u/ramenporn Update 1440 UTC:
As many of you know, DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC).
There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified.
Part of this is also due to lower staffing in data centers due to pandemic measures.
Update from /u/ramenporn
No discussion that I'm aware of yet that is considering a threat/attack vector.
I believe the original change was 'automatic' (as in configuration done via a web interface). However, now that connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally.
jine insiderske pikosky z twitteru:
Was just on phone with someone who works for FB who described employees unable to enter buildings this morning to begin to evaluate extent of outage because their badges weren’t working to access doors.

Sorry, something went wrong.
We're working on it and we'll get it fixed as soon as we can.

to budú deti facebookové(facedown-ové)....o 9 mesiacov.. :-)
hapi oni maji nekde blokaci kdyz jsi na mobilnich datech. Nekdy to muzes odeslat, nekdy ne (asi blokace nekde po ceste, jinak si to nedovedu vysvetlit). Technici me vzdy odpali, ze je to chyba v RCS v telefonu a mam si to nastavit. Sranda je ta, ze pokud mi dojde do SMS URL na share.vodafona.com/..... tak ani to nejde zobrazit v prohlizeci, pokud jsem na mobilnich datech. Hlasi to chybu DNS. Coz jasne prokazuje, ze nemam chybne nastavenou RCS! Nehlede na to, ze pokud se pripojim na wifi, tak se to odesle hned/zobrazi hned ... Testoval jsem to nekolikrat, resil nekolikrat a ani po cca roce bez uspechu to s nekym u vodafone resit ... .
jen pro informaci, me se snizil prutok dat o cca 20% presne po 18h, takze vypadek FB . Pak to zas rostlo, jak lidi koukali jinam.
Třeba skylink šel do kopru, od 20:20 do 21:20 šla odezva na jejich servery z 15ms až na 70ms. Asi se hodně lidí dívalo na bednu, když nešly ty ksichtbooky...
koukám že chybovou hlášku z roku 2020 moc neaktualizovali
jinak je pár dnů do voleb je otázka jestli politické strany, které žhnou FB kampaní za nemálo eur si budou moci nárokovat nějaké odškodné?
a už to fičí
Back online :-)
Nefunguje, jde pouze facebook a messenger. Instagram ani whattsup nefunguje stále.
