DO NOT INSTALL 9.703-2!!!
My lab system was Up2Dated to 9.703-2 Thursday evening at 10PM CDT (UTC -0500) and all connection with the outside world immediately stopped. My local connection would work normally a few minutes at a time and then everything would lock up for a few minutes. I could not identify the problem with top, but did see a lot of zombie confd processes. I lost the entire day of Friday because my wife has a big project due next week and was working via Microsoft Teams all day with her colleagues.
I will suggest to Sophos that the file be removed from the ftp site. Grumble.

Mine bonked too. I scheduled the update for early Saturday morning. Woke up to discover no Internet. I swapped in my cold spare then reinstalled 9.702-1 from a freshly downloaded ISO on the production box. Then restored a daily backup. I swapped my production box (Zotac ZBOX-CI325NANO-U) back in this morning (with 9.702-1). Performing DR every once in a while is a good thing, I guess...
