Were you enjoying the OpenSSL relatively quiet reprieve since Heartbleed?
https://isc.sans.edu/forums/diary/Upcoming+Critical+OpenSSL+Vulnerability+What+will+be+Affected/29192
Probably time to clear your schedule on Monday and Tuesday (or heck just clear the weekend) 10/29/2022 - 11/1/2022
The OpenSSL 3.0.x versions should be updated/patched - OpenSSL 1.1.1 need not apply
Happy fall patching season to you all!

The problem might be a big table (many rows) but 0 Cardinality...
use dbname; show index in tablename; | Table... | Cardinality | | tablename| 0 |
Fix the table(s):
use dbname; ANALYZE TABLE tablename;
Alteratively:
mysqlcheck -a dbname show index in tablename; | Table... | Cardinality | | tablename| 12345 |

Subject: SendGrid Incident - Mail Processing Delays - 3 October 2022 MAIL PROCESSING DELAYS Incident status: Monitoring Our engineers identified the problem and implemented a mitigation, but unfortunately, some of the delayed emails were lost during the process and could not be resent. Customers affected may notice that emails expected to be sent were processed or deferred but no further information about the status of the emails will be available.

31 August 2022, 21:34 UTCCan't connect using mysqlsh as the mysql root user?
Did you want to run the update checker and get stopped dead?
mysqlsh --mysql -u root -h localhost -P 3306 --database=somedatabase MySQL Error 1698 (28000): Access denied for user 'root'@'localhost'
If your root user is using an auth type other than "mysql_native_password",
You might have better luck adding a user with the correct PRIV and auth user type.
Hint: If you use Debian / Ubuntu, you can use the debian-sys-maint user
Search for debian-sys-maint for info on where to find the password for that user / reset it.
Plow ahead with:
util.checkForServerUpgrade();
9 August 2022, 20:53 UTCEmail - magic of the elders?
Quite a few 2fa systems using email out there these days.
Too bad the ticket system requires a successful login to create a ticket
in order to let them know their 2fa email delivery is not working.
It is a sad state of affairs when running an MTA confounds a company.
At least there is comfort in knowing the status page can deliver the "we know it is frustrating but we are working on it" message.

13 April 2022, 19:54 UTCDNS CNAME record conflicts with other types
If you have a CNAME for a subdomain, this will block the other records for that same subdomain.
E.G. subdomain.domain.tld TXT blaaaaaaablaaaaaaaaaaa subdomain.domain.dlt CNAME some.domain.other
A query for the TXT record will only return the CNAME as it short circuits the lookup - just like at the case for a bare domain CNAME record.
Reference: https://www.rfc-editor.org/rfc/rfc1034 If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types.
But as always, in the case of "should" in an RFC, you might find odd behavior based on your implementation, but it would probably
be better if the semantics of handing off the queries to the alias domain remain intact.
