first off a PC is not a server (sure email server down errors)
all email servers fail time to time , in your mind imagine , 1million spammers a second, there KILLLING it .(overloading it)_
and be happy it is not you doing service there. (i never use those I use private email , using my own domain, and never goes down.)
email has 2 path ways on a PC
1 web mail (vast browsers)
2 or app client software ,like thunderbird or outlook ,etc.
OK gmail not down, thenb what./?
my guess is web mail fails using EDGE?
no browser told so I guess wild EDGE< (or chrome. or firefox)
I use fire fox for decades now zero failures, ever
my wild guess is wifi fails
as it loves to do
so connect the PC to the router, via ETHERNET cable.
and see it work for decades and never ever fail.
or
or upgrade you wifi a real AP , system, like schools uses
I use Unifi AP. and is powerful and frankly just works.
or get private email that the free junk
pay for it. best is paid, not free,. free causes stolen personal info, and exploitation .
and win,
google that
3billion hits.

or buy your own domain name and pay for it here.
cheap/
https://www.interserver.net/
end the cycle of pain get your own domain,
no web site needed just the account. the in Cpanal create lots of email there. even 100 if you want
and all auto transfer to one email account. if you want
and works web mail and on with my great free THUNDERBIRD.
sporadically means what?, 1 time per day or week or year?
or ask them? we are not gmail and if down , on 2 PCs Gmail is down. (wifi good)
as easy as that.
