Kent County Council said Dover ferries and Le Shuttle will not take passengers without a booking today because of the outage.
The council said: “If your start to the summer holidays has been impacted by the IT outage, you may be thinking of swapping a plane for a channel crossing.
“But both the ferries out of #Dover and Le Shuttle are not taking turn up passengers today.
A spokesperson added: “Please make a booking before heading to the port.”
The Channel port has been swamped with “hundreds” of passengers after 5,000 flights were grounded in the worldwide IT meltdown.
The glitch caused dozens of flight and train cancellations across the UK and brought parts of the NHS to a standstill.
Experts warned that it could take weeks for systems to fully recover – with more flight delays and cancellations expected this weekend.
London Gatwick, Heathrow Airport, Manchester Airport and Belfast International Airport have all said they could be affected.
The airports said passengers should check with airlines for any delays or cancellations before travelling over the weekend.
A whopping 167 flights scheduled to depart UK airports were axed yesterday – with a far greater number delayed.
Another 171 flights due to land in the UK were cancelled following the technical glitch.
Aviation analytics firm Cirium said 5,078 flights – or one in 20 of those scheduled – were cancelled globally yesterday.
Disruption to pharmacy services is likely to continue through the weekend, even when systems are back online.
Pharmacies across the UK have been swamped with a backlog of medicine deliveries.
National Cyber Security Centre expert Professor Ciaran Martin said the chaos could drag on for days.
He said: “The underlying problem is fixed and the fixes are being implemented.
“Some industries can recovery quickly. But others like aviation will have long backlogs.
“That said, I’d be surprised if we were still facing serious problems this time next week.”
Experts warned users to “remain vigilant” against potential scams as systems recover.
CrowdStrike and the NCSC are warning people to be especially wary of phishing scams exploiting the confusion.
The NCSC said: “Note that an increase in phishing referencing this outage has already been observed.
“Opportunistic malicious actors seek to take advantage of the situation.”
The outage knocked around 10 billion US dollars (£7.8 billion) off CrowdStrike’s market value.

What sparked the tech meltdown?
By Ashley Armstrong, Business Editor
A minor tech tweak has been blamed for the world’s biggest IT outage.
Experts have warned that yesterday’s disaster highlights how reliant modern society is on technology and how vulnerable it is to glitches.
The “blue screen of death” on many Microsoft Windows computers was caused by a software update from a US cyber security firm called CrowdStrike.
Microsoft said that Windows devices running the CrowdStriek software “may encounter a bug check (BSOD [blue screen of death]) and get stuck in a restarting state”.
CrowdStrike, valued at over $80 billion before yesterday’s crisis, counts 29,000 companies as customers including schools, hospitals, supermarkets, airlines and banks.
The firm was quick to confirm the chaos was not caused by a cyber attack, but an update to its software.
When CrowdStrike’s software, called Falcon Sensor, was sent out automatically to its customers there was an error in the coding which meant Microsoft computers would not restart. The issues did not impact Apple Mac computers.
George Kurtz, CrowdStrike’s chief executive, said the cause of the problems was a “defect found in a single content update for Windows”. CrowdStrike’s security software is meant to detect viruses and online threats and is meant to block them. Yesterday it said that it was rolling back the update to the software.
Shares in the Austin, Texas based company plunged by 14 per cent as soon as US markets opened, wiping $10 billion (£7.7 billion) off the company in an instant.
