This is not a TalkTalk error and has caused issues for others on a variety of websites across the board.
There is a suggestion that your system may have been compromised. Have you by any chance clicked a link on a suspicious email recently such as the one seemingly from TalkTalk asking for your account to be varified?
Run a full virus scan and malware scan to see if there are any issues.
Also do a search on edgesuite errors, you may find a solution on one of the may responses there.
Sorry can't be of any more help.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
