- replace "Labs" by "Cloud Services" and https://wikitech.wikimedia.org/wiki/Wikitech:Labs_Terms_of_use by https://wikitech.wikimedia.org/wiki/Wikitech:Cloud_Services_Terms_of_use (pointed out in T202476)
- replace "Operations" by "SRE"
- replace "via either phone or IRC" by "via either phone or IRC in the #wikimedia-operations channel on Freenode"
All done, added irc options as well as clarified that real time is preferred over email. Added in the security@ alias in case IRC is not an option (as it hits a lot of folks.) All references to lab have been replaced with cloud/WMCS (along with an statement of what WMCS is) and changed ops to SRE where relevant.
