We gave access to a contractor to install a firewall and somehow while he was doing it he fracked something up. Everything went off-line about 24 hours ago and we are effectively out of business until I solve this and the person who messed up the thing is not returning calls.
I found a few errors. First, I'm not a server guy - I can look at log files and normally everything runs fine. All 'services' are running according to 1and1 server monitoring and mail is being delivered just fine. The whole thing was off-line until I (probably stupidly) updated the kernel from 6.2 to 6.3 this morning and I got everything back except the http access.
All the domains (~200 of them) are returning a 403 error and nothing is recorded in the access log.
On every restart I see this error in the messages log file:
init: Failed to spawn ttyS0 main process: unable to execute: No such file or directory
and a little later these:

And something is wrong with the Named/BIND resulting in the same error for all domains:
zone DOMAINEXAMPLE.com/IN: loading from master file DOMAINEXAMPLE.com failed: file not found zone DOMAINEXAMPLE.com/IN: not loaded due to errors. _default/DOMAINEXAMPLE.com/IN: file not found
I'm pretty sure this is not enough information to solve the problem, but I'm willing to engage someone who can work this out for me.
Any help would be greatly appreciated.
